Your Baby at 12 Weeks Pregnant

Baby’s growth and size

Your baby is now just over 2 inches in length and tips the scales (well, maybe not tipping them just yet!) at half an ounce (give or take). 

What’s new developmentally? 

All of baby’s major organs, body parts, and physical features are in place. Your baby will spend the next 28(ish) weeks growing and maturing all of these systems. 

Fun facts about your week 12 baby

  • Baby is now developing reflexes 
  • Baby can make a fist with their hands and curl their toes

12 weeks pregnant ultrasound

There are a few reasons why you might be receiving an ultrasound at 12 weeks pregnant. You should have had an initial ultrasound to confirm your pregnancy and verify your dating by this point, but if you haven’t then this will be done.

The nuchal translucency screening tests for chromosomal anomalies like Down syndrome and is typically performed between weeks 11 and 14. Keep in mind, this is just a screening and will require additional testing to confirm a positive result.

To learn more about genetic screening tests, high risk pregnancies, and more, take a listen to my podcast interview with OBGYN, Dr. Marta Perez here.

If you have an ultrasound done at 12 weeks, you can expect your provider or sonographer to measure baby’s length from the top of their head to their bum, a measurement known as the crown-rump length (CRL). The CRL is used to help estimate and confirm gestational age.

You should also be able to hear and see baby’s heart beating for the first time too, which makes this one such a special and memorable appointment.

Why is 12 weeks safe to announce pregnancy?

Many women wait until they are in their 12th week to announce their pregnancy. Why is this you might ask? According to this article from ACOG, “Approximately 80% of all cases of pregnancy loss occur within the first trimester.” For this reason, a lot of women chose to keep their pregnancy to themselves, family, and possibly close friends, until they are in or through week 12 or 13.

There is no right or wrong answer when it comes to announcing a pregnancy. When someone chooses to announce is personal and no one else’s business but their own!
