Here’s what to know when you’re 12 weeks pregnant:

Your Baby at 12 Weeks

The end of the first trimester is near! Here’s what’s going on with baby at 12 weeks pregnant.

How big is baby at 12 weeks?

Your baby is 2.1 inches long and weighs .49 ounces this week. That’s about the size of a roll of film. Wondering what fruit is the size of baby at 12 weeks? They’re about the size of a lime.

Baby’s Development at 12 Weeks Pregnant

  • Major growth: Whoa! Did you notice your baby doubled in size over the past three weeks? At the ninth week of pregnancy, they were only about an inch long, and now your 12-week fetus is almost 2 inches.
  • Digestive progress: Your baby’s intestines are fully developed, and they’re starting to change position, from the umbilical cord into their rightful place, the abdomen.
  • Cuter face: If you could see inside your 12 weeks pregnant belly, you’d see baby’s face is looking more like… well, a baby, than ever before. This week, the eyes and ears are in (or close to) their permanent spots, making your babe camera-ready for the upcoming ultrasound.

Your Baby’s Reflexes

At 12 weeks pregnant, your baby is developing reflexes. Eyelids are starting to open and close, and they’re sucking with their mouth. Later, fingers will open and close, and toes will curl. Most of these reflexes start to develop in utero and stick around for a while after they’re born. Then eventually, they’ll be replaced by voluntary movements. Here are a few you may notice post-birth:

  • Moro reflex: Newborns seem to startle easily! When there’s sudden movement or a loud noise, they’ll throw out their arms and legs and then pull them back in toward their body. Your baby already has this reflex (it starts at about the 8th or 9th week of pregnancy), and it should go away by the time they’re four months old.
  • Palmar grasp: Ever notice how a newborn will hold on to a finger or almost anything else you put in the palm of their hand? Right about now, your baby already has this reflex. It’s a strong reflex until about two or three months post-birth and then disappears around the first birthday.
  • Babinski reflex: When you stroke the bottom of a newborn’s foot, their toes will fan out, and the rest of the foot will curl. So cute! This reflex will develop around the 18th week of pregnancy and go away by six months post-birth (though sometimes it can last until 2 years).

💛 Congratulations 💛

There are 196 days until baby is due.

Unless your first trimester genetic screening is this week, you probably won’t have a 12 weeks ultrasound. But if you do, here’s an idea of what baby might look like:

12 Weeks Pregnant Symptoms

You can chalk pretty much all your symptoms up to hormones at this point. Your HCG levels are likely super high at 12 weeks pregnant, but they should start to level off very soon.

  • Headaches: At 12 weeks pregnant, headaches can be triggered by the fact that your hormones are raging like you’re back in ninth grade. Dehydration and drops in blood sugar can contribute, too, so drink plenty of water and snack regularly to prevent them.
  • Darker skin spots: Patches of dark skin on your face—a.k.a. the mask of pregnancy/melasma/chloasma can appear. That’s because hormonal changes have upped the amount of melanin, which creates pigment, in your body. Remember, your skin is more sensitive to sunlight now. So limit your time in the sun, and wear a hat, sleeves and SPF 30 or higher sunscreen.
  • Dizziness: Those lovely hormones also relax blood vessels, which means better blood flow to baby, but possibly less to your own brain 🙄, since your blood pressure may be lower than usual. Keep up the snacking to avoid low blood sugar, which can also cause of dizziness or lightheadedness.
  • Morning sickness: You’re tired of feeling sick, we know, but remember: you’re still in early pregnancy. Morning sickness can linger until you’re comfortably into the second trimester (which officially starts week 14). Just let the doc know if you can’t keep any foods down or if it keeps up over the next few weeks.

Heartburn During Pregnancy

Early pregnancy is notorious for morning sickness, and the rest of pregnancy is big on heartburn. That’s because the hormone progesterone relaxes the valve between the stomach and the esophagus, allowing stomach acid to come up. (Fun stuff.) As your baby grows, you might get it even more since your little one will eventually crowd your stomach and intestines.

To prevent heartburn, be strategic:

  • Eat small meals about five or six times a day.
  • Don’t lie down within an hour after eating. Try to eat dinner early—like, at least three hours before bedtime.
  • Avoid spicy, greasy and heavy foods, which can trigger heartburn. And pay attention to your own personal triggers—chocolate, caffeine and carbonated beverages are no-goes for some.
  • Chew food extra thoroughly before swallowing.
  • If you do feel the burn every now and again, you can try eating a bit of yogurt or drink milk to soothe your tummy. Antacids like Tums and Rolaids are usually considered fine to take, but avoid anything containing aluminum or aspirin. There are prescription meds for severe cases too. And it’s always best to check with the doc before taking anything, even if it’s OTC.

Fun Fact

Women with heartburn are more likely to give birth to babies who have a full head of hair.

Your 12 Weeks Pregnant Belly

During this week of pregnancy, your uterus is starting to grow up and out of your pelvis, which explains why your pants are getting tighter. Sure, you might look more like you have a beer belly than a baby bump right now, but that will change quickly in the coming weeks.

If you have a prenatal checkup this week, you’ll probably be able to hear your baby’s heartbeat with a fetal Doppler. Amazing!

Top Tip for 12 Weeks Pregnant

Stall on buying maternity pants by using a hair tie or a rubber band to hold your jeans closed. Put the rubber band through the buttonhole and loop both ends around the button. Ta-da!
