Is about two-and-a-half inches long. So still in the lemon/lime range.
Already has pretty much every structure, organ and system needed for life by this point. Everything will continue to develop and mature, but your baby really is a perfect little miniature human being.
Reproductive organs are distinctly male or female.
Can officially be Bugged By You. Reflexes have developed, so if you push on your uterus, your baby will squirm and move in response. You can’t feel it, but it sure is fun to imagine getting flipped off by your foetus.
You are:
Are you feeling better? I hope you’re feeling better. I keep thinking I’m feeling better and then I’m not. And then I am again! And then I smell whatever it is that you’re eating over
Have a big uterus now — too big to remain all low in your pelvis. It’ll sort of grow and migrate upwards during the second trimester. Pros: you won’t have to pee so much. Cons: your baby will better be able to land many, many kicks to your internal organs.
Especially if this isn’t your first pregnancy and/or haven’t lost weight due to morning sickness. The whole waist-butt-thigh region is spreading, and it’s best to just go with it and be comfortable.
13 WEEK
Your Baby:
Is about three inches long, the size of a jumbo shrimp,
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.
Will look less and less like a Big Giant Head and more and more proportionate as the next weeks tick by.
You are:
Are probably not puking anymore?
Are probably not as tired anymore?
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.
14 WEEK
Your Baby:
Is about the size of your fist, unless you have giant man-hands.
Has a strong, whoosh-whoosh heartbeat that can usually be found pretty easily now with a Doppler. It’s much faster than yours (between 120 – 160 bpm),
Has probably started sucking its thumb.
You are:
Should be noticing a definite decrease in some of the more crap symptoms from the first trimester, although fatigue and nausea do tend to stick around a little longer for some women.
Probably aren’t as bothered by breast tenderness anymore, although your breast will continue to grow in size in the weeks and months ahead.
If this is your first pregnancy, you may FINALLY feel like you’re starting to “show” with a little belly pooch.
If this is your second (or third or fourth or etc.) pregnancy, you’ve probably been in maternity clothes or been rubber-banding your pants for a few weeks already.
