Week 13

Your Baby:

  • Is about three inches long, the size of a jumbo shrimp, or a very small ramekin of tartar sauce.
  • Has his or her own unique fingerprints already.
  • Has intestines on the INSIDE of his or her body. (They start developing outside the body, in the umbilical cord, and then sort of…migrate up to their proper home around 13 weeks. I know. Biology is WEIRD, dude.)
  • Will look less and less like a Big Giant Head and more and more proportionate as the next weeks tick by.


  • Are probably not puking anymore? But don’t freak out if you still are? I generally feel iffy until around week 16, although right now I’m only suffering from the occasional dry heave (on Tuesdays. Every damn Tuesday.) and have actual full days where I want to eat everything in sight because it’s all so gooooood.
  • Are probably not as tired anymore? Unless you are me? I still can’t seem to get enough sleep or make it through the day without a catnap. Although maybe I am just very lazy.
  • May start glowing soon, like everybody always talks about. The “glow” is actually just hormonal changes in your skin’s oil production, but it seems most people find it dewy and lovely instead of…ew, gross, oil.
  • Your hair and nails might be changing as well — a lot of women stop shedding hair during their pregnancies, leading to very thick heads of hair that may also grow faster. Fingernails tend to get stronger and longer as well, which I can personally attest to BEING AWESOME.

Welcome to the second trimester! Well, the second trimester as defined by MOST pregnancy books and calendars, although I believe there may be one or two that count week 13 as part of the first trimester (cough cough BabyCenter Essential Guide to Pregnancy and Birth cough), but they can suck eggs, frankly. I would never do that to you. We are in the second trimester, baby. I promise it gets better.

I went and bought some serious maternity clothes this weekend — something I swore I wouldn’t have to do because hi! I’ve been pregnant before. I should already have buckets of maternity stuff. Except when I started digging through it all, I found that I didn’t have very much.

Since my last pregnancy was going to be my last and only pregnancy, I refused to spend money on maternity clothes. I bought everything on clearance, from the cheapest stores possible, and then borrowed the rest. So now I’m dealing with a three-fold problem:

1) I gave all the hand-me-downs back and have been unable to procure a new clothing source, because everybody else I know is either pregnant right now or was pregnant in the winter.

2) All the cheap stuff I bought barely made it through one pregnancy, and is practically disintegrating.

3) Also, wow, I wore THAT? THAT is ugly. I do not want to wear THAT again.

Add on to this a mysterious weight loss that I was not aware of — I appear to be about 10 pounds lighter and a full size smaller than I was when I started my first pregnancy — and even the few nice pieces that I splurged on last time are way, way too big. Oh! And! The stuff I own is more suited for a professional office. Which I do not go to anymore.

So I have about eight pairs of (way too big) khakis that require regular ironing (hah!), four pairs of cheapo black stretch pants with holes in the crotch, and ONE WHOLE PAIR OF JEANS. That are also way too big. And a lot of pink shirts. I…really dislike the pink shirts.

So I guess the lesson for all you first-time pregnant ladies out there is this: Don’t always go with the ultra-cheap stuff, because no matter what you think now, you may very well end up needing to wear it again, but also don’t always go with the ultra-expensive stuff, because no matter what you think now, there’s no guarantee that you’ll be able to wear it again.

Does that help? Glad I could clear that one up.

So fine, I snagged a 15% off coupon at my doctor’s office for a local fancy-like maternity boutique in the area and splurged on an amazing pair of jeans (Paige and Citizens make maternity versions of their jeans and really are a far cry from some of the droopy-butt stretch-pants some stores try to pass off as “denim”), a really cute dress, and two shirts that I love and have already worn like, seven times in the course of three days. I’ve filled out my maternity wardrobe with plenty of comfy clothes for around the house and quite a few non-maternity items from H&M and Old Navy and Target (seriously, I’m rejoicing over some of the baggy long tops and dresses I’ve gotten, but what non-pregnant girl would EVER want to wear stuff that will easily cover a six-month-old fetus?).

So basically: build your maternity wardrobe just like your regular one. Mix and match high-end with bargains, invest in the stuff you know you’ll wear to death (like jeans or dress pants or even a suit if you need it) and don’t cut corners to the extent that you end up cringing over photos of the ghastly stuff you wore. Remember you’ll wear maternity stuff after the baby is born too, and will probably want to wear something other than breastmilk-stained yoga pants occasionally. You know, if you’re ever feeling fancy.

(Oh, and if you’re still cringing over the thought of spending money on maternity clothing and are also coming up dry on the hand-me-downs, check around your area for a mother-and-baby consignment shop. These are great for scoring the higher-end stuff AND for getting some of your money back when you’re done with your own clothing.)

Oh Yeah, THIS: please let me make it through the night without waking up to pee soon. please let me make it through the night without waking up to pee soon. oh please, I cannot take the waking-up-to-pee thing much longer.

New This Time Around: I feel like I am kind of half-assing this pregnancy, especially when it comes to nutrition. I’m just…eek. Not caring at all. I’ve forgotten my prenatal vitamin more times that I’d like to admit, and have eaten some bonehead things out of sheer absent-mindedness. This weekend we went to a very nice dinner party at a friend’s house, and I was halfway through my scallop-and-beef tartare with a raw quail egg cracked on top before I finally stopped and looked at it and went, “OH. RIGHT. CRAP.” I’m definitely more relaxed about stuff like an occasional tuna fish sandwich or some nice cold cuts from a gourmet deli, but I have to admit that I sometimes do need to wake up and pay more attention to this stuff.

    I try and get Tim to take me to Mexican restaurants based solely on their margarita worth. And then he always has to remind me that I can not have any margaritas, and so I have to settle for a spicy chicken sandwich instead.
    I also think I need to tape my vitamin to my forehead to remember to take it. Which might be helpful, because that glow business? Unless dry, scaly, broken out skin counts as “glowing” I don’t have shit to show for that supposed side effect. And ripping the tape off might help some.

    I’m a girl of generous belly at the best of times, so I have been rejoicing at this new style with lots o’ fabric in front since WAY before I got pregnant!

    I love second trimester. I heart it. I want to marry it. First trimester was completely miserable. Very little throwing up, but constant nausea, headaches, and violent psychological reactions to every single kind of food in the world.
    Now, I feel better than I have since high school, when I was in sports and all in shape and stuff. I want to be second trimester forever. My sister sent me buckets of clothing. It pays to have a sister of the same size and body type who also happens to have better taste than I do. I have more cute pregnancy clothing than I do cute normal clothing.
    Unfortunately, I’m carrying so high that none of the maternity pants fit (though all my normal pants are too small). It’s actually a little bit funny. I wear maternity pants, they fall down. I wear regular pants, and the waistband pushes the little fat pouch up and out so it just looks like I have a giant fat roll. Charming!
    I think I maybe need to stop leaving such ridiculously long comments here. I just can’t stop talking. This is what happens when I can eat, sleep, and not feel sick all day. So, I’m sorry. I’m in a constant state of giddiness.

    How do the food comparisons go from lime to medium shrimp to lemon? It seems like there are pretty drastic differences there. I don’t get it.
    I completely lucked out and got a 45 lb box of clothes shipped to me from a good friend back home full of almost every maternity item I would possibly need and there’s more on the way. It’s from a friend who has better taste than me so I will actually have the oddness of dressing better when I start maternity clothes. I got casual clothes, dressy clothes, velour hoodies and yoga pants, etc. I am going to kiss that girl when I see her in December. I can’t stand shopping so this is the best thing that could have happened to me. I’m 13 weeks yesterday and things are a little tight but I think I still have a while before I need to switch to the borrowed clothes.

    Great post (maternity wardrobe advice!)
    Here’s what I’ve learned from Pregnancy #1 that has caused me to shift my wardrobe decision-making during Pregnancy #2:
    Most of the affordable maternity stuff out there (not naming any particular brands here) is poorly made, will not wash well, and is extremely “trendy” (read=will look totally dated by the time you hit pregnancy #2)
    O.K. When you are ready to go back to work, you will also need an entirely new PostNatal wardrobe (even if you lose the babyweight miraculously fast, you will have these giant goddess nursing orbs that will not- I repeat will not- fit your normally proportioned tops).
    With these two observations in mind, and embarking on Pregnancy #2, I decided not to go the maternity clothing route (o.k. you really do need to get some maternity pants and jeans). I have bought all of my tops a size or so bigger, or in a style that can snugly accommodate a growing belly and breasts. I get higher quality pieces (not necessarily designer- Loehmanns, Marshalls, are great during pregnancy) At work I practically live in the same three-four or so rayon skirts that can sit low under my 8-mo prego belly. Add a cute top and you are good to go! Oh, and gauchos! Wow, they are like your total bestfriend during and after pregnancy (they walk the thin line between slobby weekend pants and practical on the move mommy chic).
    Sure I do have some maternity basics, most of which were totally scavenged from Pregnancy #1, but it was downright depressing to note how much of the stuff I originally bought for $$$ was totally unwearable. I now feel confident that I can transition the clothes I have bought into at least a few extra postpartum months.
    Oh yeah, and whats up with the pants being way too big the second time around?

    I start week 13 tomorrow. I am on my 2nd pregnancy, and I agree about the maternity clothes. I spent way too much money on clothes the 1st time around, and most of the clothes that I had were for the office. I now stay at home with my son, and I will be staying at home after this baby is born too. So the few shirts that I have that are casual are being worn out. When I am at home, I stay in my comfy pjs if we aren’t going out.
    The only bad thing is that I am looking forward to buying some new maternity clothes within the next few weeks. And I am sure that I will make the same mistake that I did the 1st time. But I am hoping that I will be smarter with my selection and $$ decisions.

    I’m 13 weeks tomorrow, and I just realized today that although I FEEL bigger, I’m actually losing weight. I’m like 3 pounds less than I was when I got pregnant. I haven’t been INCREDIBLY sick — I think I’ve only thrown up a handfull of times — and I’ve been really careful to eat every few hours, because it helps keep the nausea at bay.
    I’m scared. Shouldn’t I be gaining? Why am I losing weight? Being a holiday weekend, I can’t call my doctor until Tuesday… then I fly across the country on Friday. What if there’s something wrong?
    Editor: When in doubt call your doctor. All doctors have a service answering the phone to attend to emergencies and pregnant women who must speak right now. I’m sure your doctor receives calls on the weekend (even holiday weekends) from panicked moms-to-be.

    I hit 13 weeks on Thursday. I have pretty good energy on the weekends but getting up early for work during the week drains me. And every night I an exhausted by 9 or 9:30. But other than that, the appetite is coming back. As for the clothes, I’m in the inbetween stage. A lot of my “normal” clothes are tight but maternity clothes are big. I did get a HUGE tub of maternity clotes from a friend yesterday so I’m glad I don’t have to buy a whole new wardrobe. She’s a little smaller than me but it doesn’t really matter in maternity clothes. Sweet!

    I am tiny and like fitted clothes, so am already going through the local Old Navy for fluffy shirts I normally never wore because I would look pregnant. Sadly, I must buy a whole new wardrobe mostly because I am short and I can fit into no one else’s stuff. Stupid short legs. However, my sweet, sweet, cheap, husband, has not batted an eye at my $$ shopping excursions. Which is a first.

    I found that the local Thrift stores have a limited quantity but cheap prices (ofcourse) on maternity wear. i was luck enough to go into a consignment shop and talk to the owner for a bit. She brought me out 2 boxes of maternity weatr to go through. got alot of really cute timeless shirts and 4 pairs of nce dressy pants i can wear to work. Also a great pair of Jeans that actually look like jeans. Goint to hit up the other two consignment stores in town to fins more. I am probably the cheapest person when it comes to clothes anyway.
    I am also going to trendy stores or department stores to their clearance racks and buying the “makes you look pregnant” clothes for when I cma bit later this year. That is Key… nice shirts for $2 or $3.
    Also loving the belabands for those pants that just don’t quite button and the pant extender works pretty well too.
    All in all feeling pretty good, but ask me in 20 minute that could change.

    I love reading all of this. It comforts me in so many ways. I am vacationing in Mexico for three months and on my way home. Traveling and so thankful to not be sick and my pants all still fit. I don’t know a single thing about being pregnant and I am so glad to have this website to follow along with.

    Hahaha the waking up to pee thing… yes! Plus I try to be quiet so the toddler doesn’t wake up. The food thing I also did. I scarfed down about 6 or 7 buns with italian cold cuts before realising that that is actually raw meat. Oh well. I enjoyed them a lot.

    I’m almost 13 weeks and just have gained a weird high fat roll just below my belly button. Otherwise I look normal. I was pretty sick the first trimester and haven’t gained weight but my stomach looks like I ate 15 burritos and they all got stored under my belly button. So weird. I actually can’t wait to look more pregnant. I didn’t need maternity clothes with my first pregnancy but might this one! Just excited to get past the awkward might be getting fat stage.

    What is this weight loss everyone talks about? I am just into my 13th week and I’ve gained more weight than I’d like to admit. Soooo much weight with no regards to the amount of puking I’ve done. Soooo much puking. Granted I was underweight when I got pregnant- little bundle of joy according to my math should be 10 pounds by now and deff not the size of a shrimp.
