Pregnancy: Week 12
  • 2 Shares

12 Weeks Pregnant

What to expect at 12 weeks pregnant? By now, the first trimester of pregnancy is complete, and your baby weighs a full half once already! Fetus measures about two and a half inches crown-to-rump, and is the size of a lemon— quite impressive, isn’t it? But despite this measurement, your womb is still quite small, and your figure barely shows that you’re pregnant. But don’t hold onto your skinny figure yet — your tummy is getting bigger every day, so you will soon have a beautiful bump! Time to shop for maternity clothing!

What to Expect:

All those hormones in your body are probably leaving you a bit emotional, although you’re already just one week away from the second trimester.

  • Luckily for you, morning sickness if no longer as bothersome as it was before, although you may sometimes feel a little nauseated. The good news is, now you can eat more than usually without throwing up everything you put in your mouth.
  • When you're 12 weeks pregnant, your uterus has grown a great deal by week 12, and your doctor can now feel the top of it low in your abdomen, right above the pubic bone. Your waistline has already thickened a little, although probably not as much as you might have expected. At this point, you will certainly feel more comfortable in maternity clothes since your tummy keeps getting bigger.
  • During the twelfth week of pregnancy, many women start to experience heartburn, which manifests as a burning sensation going from the breastbone to the lower throat. If you’ve been dealing with heartburn before pregnancy, your symptoms will get worse during week 12. This is caused by the placenta producing a lot of progesterone, which relaxes the valve between the esophagus and stomach. When you lay down, gastric acid seeps back up the pipe, causing that burning sensation. Talk to your doctor if you have heartburn to learn about ways to ease it.

Your Baby at 12 Weeks

How big is a baby at 12 weeks? During this week, your baby starts to develop reflexes. He/she will soon be able to open and close his fingers, curl his/her toenails, and even make sucking movements with his/her mouth. Right now, your little one’s intestines will move to the abdominal cavity, protruding into the umbilical cord. Soon, the kidneys will start to excrete more urine as well.

12 weeks pregnantThe brain is developing at a rapid pace, with nerve cells multiplying and synapses forming furiously. The eyes are now located on the top of his little head, whereas the ears have moved to their final location. During this week, the baby’s skeleton is still made of cartilage rather than bones, which will continue to harden over the next few weeks. Interestingly, a baby is born with 300 bones, but since many of them fuse together as he/she grows, there will be only 206 left when he/she reaches maturity. The eyelids will remain fused shut until week 26-27. The most exciting part is that, if you prod your tummy, your new resident will wriggle in response, though you won’t be able to feel it right now.

Pregnancy Tips

  • Week 12 is the best time to start doing pelvic floor exercises — they prepare you for labor and birth, and also protect you against urine leaks, which are very common after delivery.
  • Since your appetite has returned, you will feel like eating more than usually — but don’t just give in to food cravings! Keep eating a healthy, balanced diet to avoid weight gain, and exercise regularly to stay fit.
  • It’s also the prime time to have a budget discussion with the baby’s father. You need lots of baby clothes, diapers, food, toys, and so much more after your little one is born, so early planning will do you many favors!
