Your baby at 12 weeks pregnant
What's happening in there
- Your baby is the size of a lime.
- You’re officially in the last week of your first trimester.
- The countdown continues: you’ve got 28 weeks to go!
What happens during the 12th week of pregnancy?
- All systems go: Most of your baby’s internal systems are formed by week 12. The kidneys are functioning and can turn any amniotic fluid consumed into urine. That little abdomen is now large enough to hold the intestines, and the digestive muscles are contracting in preparation for being able to eat and digest after birth. The liver is producing blood cells now too, helping to really accelerate development.
- Get ready to make some noise: At week 12, your baby’s vocal cords are developing, preparing for giggles, gurgles, and the inevitable crying when you finally meet.
- Prepping for that close-up: By week 12, your baby’s profile will be visible on a sonogram, with all the changes to their face discernible.
- The internal computer has started up: The corpus callosum is developing. This is a bundle of 200 million axons, or nerve fibers, that coordinates motor, sensory, and cognitive functions between the right and left sides of the brain.
- Your baby is growing - and is actually not in the embryonic stage anymore. At eight weeks from fertilization, the embryo has transitioned to the fetus stage. Time is going fast!

Week 12 pregnancy symptoms
During week 12 of pregnancy, your body is changing quickly. As your baby grows, you will too, and there are certain pregnancy symptoms you may experience at this time.
8 common week 12 pregnancy symptoms
- Burping, bloating, and flatulence are part of the side effects of pregnancy hormones that relax the digestive tract. Avoid beans, fizzy sodas, candy, and fried foods.
- Hooray, you’re not feeling sick! Instead, welcome to progesterone’s new trick—dizzy spells. This pregnancy hormone can cause your blood vessels to widen to increase blood flow to your baby, but it slows its return to you, causing lower blood pressure and light-headedness.
- You may be producing excessive saliva. It’s an odd symptom, but rather than drooling, try chewing gum!
- Your sex drive can drop considerably. It’s completely understandable at this point as your body is playing so many tricks on you both physically and emotionally..
- At 12 weeks pregnant, headaches, driven by—you guessed it—hormones, are common.
- You may start to experience what is called round ligament pain. This pregnancy symptom, which feels like sharp jabbing discomfort in your abdomen or hip area, is caused by the extra pressure put on your ligaments as your belly expands and stretches. Certain exercises may help. Just be sure to get an OK from your doctor first.
- Vaginal discharge will continue throughout your pregnancy.
- Your skin may be changing. You may notice the “mask of pregnancy,” or chloasma, appear in brownish patches on your face and neck. These will usually lighten or disappear after your baby is born.
Will I be showing at 12 weeks pregnant?
Women at 12 weeks pregnant may be showing, especially if they’ve had previous pregnancies or are carrying multiples. Is this your first baby? Your belly might be sporting that telltale bump, but you may have to wait a little longer. The pregnancy belly pop will be here soon enough.
3 expert tips for a healthy and safe pregnancy
Being 12 weeks pregnant is an important time for you and your baby. Here’s some more expert-recommended advice on how to adjust to this new stage and keep you and your baby safe.
- Fuel their mind: Now that your baby’s brain and nerves are developing rapidly, you need to fuel that growth with the right foods. Combine a healthy diet with prenatal vitamins that include DHA (docosahexaenoic acid) to nourish your baby’s fine motor development and vision.
- Slow and steady wins the race: Your joints are probably loosening up from a hormone called relaxin, which will eventually aid the opening of your cervix. For now, it can also loosen ligaments throughout your body, making you more prone to injury. So take things slow and steady, whether you’re working out or carrying groceries.
- Don't let the flu get you down: Be sure to get a flu shot; the CDC recommends vaccination for all moms-to-be.
