12 weeks pregnant

Hey, you lucky lady! Fortunately for you, 12 weeks pregnant is when many women are feeling noticeably better than they were earlier in the trimester.

It should be pretty smooth sailing from now on, compared to what you’ve been dealing with up to pregnancy week 12. But there are lots of changes happening really fast, both to your little one’s body and yours. So take a good look at this quick guide that will walk you through everything you need to know about week 12 pregnancy.


12 weeks pregnant: Put your hands in the air like you just don’t care!

With all the movement that your growing baby is now capable of, it’s remarkable that you can’t feel a thing! That’s because he’s still pretty small—between 2 and 2.5 inches, or the size of a lime. Since you can’t expect your senses to tell you, here’s what your little guy is up to while you’re 12 weeks pregnant: 

  • He’s wiggling and moving around
  • He can open and close his fists, and even flex his feet!
  • His facial muscles are moving too, but he won’t open his eyes anytime soon
  • He weighs about half and ounce, but he is nearly double the size he was a few weeks ago
  • His vocal cords are forming (Too bad you’ll have to wait a few months to hear him shouting!)
  • The organs and organ systems are all set up, so the rest of your pregnancy will be time for these to mature
  • The kidneys are working, so urine production begins
  • The digestive system begins “practicing” by flexing and contracting
  • He has bone marrow, which is busy making white blood cells
  • The pituitary gland is fully developed and begins producing hormones


12 weeks pregnant: Nausea—in the clear!

Although so much is happening with your little one during pregnancy week 12, this is when you should start to feel much better than before in terms of early pregnancy symptoms like nausea, breast tenderness, fatigue, and food aversion. You can finally start to enjoy meals again!

You’ll also probably feel the need to pee much less frequently than before. This is because your uterus, which is now around the size of a grapefruit, has migrated upwards closer to your intestines and farther from your bladder.

Unfortunately, though, at 12 weeks pregnant, you will most likely still be experiencing some negative symptoms, such as:

  • Dizzy spells
  • Bloating
  • Constipation
  • Changes in sex drive, potentially with lack of libido
  • Still some fatigue
  • Gas
  • Headaches
  • Heartburn


12 weeks pregnant: Last chance for the booking appointment!

By 12 weeks pregnant, you’ve most likely already had your booking appointment and dating scan, which you can learn more about in the 8 weeks pregnant article. If you haven’t already had this very important appointment, don’t wait any longer! You need to discuss the details of your pregnancy with your doctor and give him your medical history so that he can keep track of your baby’s development and be on the lookout for any probably genetic problems or other abnormalities.

If your doctor sees any red flags in your family history, medical history, or age (i.e., being over age 35), he may want to order a combined test for you. You can learn more about the combined test in the 11 weeks pregnant article, but it is essentially a series of tests to look for genetic abnormalities, such as Down Syndrome. You can have it anytime between 11 weeks plus 2 days pregnant and 14 weeks pregnant plus 1 day.

By pregnancy week 12, you could already be showing the beginnings of a baby bump. You also could not. This stage of pregnancy is different for all women, and is even different from pregnancy to pregnancy. (Typically women who have already been pregnant before begin to show a little bit earlier.) You may find yourself in an awkward stage where finding clothes to wear is extremely difficult. 

Probably, most of your jeans and tight-fitting clothing aren’t working for you anymore, but you’re not quite ready for maternity clothes. Some of the best options for women around 12 weeks pregnant are wrap dresses, empire waists, and stretchy materials—hello, yoga pants! If you need to dress more professionally, try blazers without buttons, loose blouses, and skirts with elastic waists. These should all get you over the hump until you fit properly into maternity clothes.


At 12 weeks pregnant, you’re probably feeling relieved to be heading toward the end of your first trimester—and spending less time running to the bathroom! The rest of your pregnancy will be a joyride compared to what you’ve been through, so sit back and enjoy the ride!
