Week 9
Baby’s growth and size
Congratulations, your embryo is now a fetus! Your baby is measuring about an inch and a half in length and weighs around .14 ounces.
What’s new developmentally?
Baby’s vital organs have developed and started working but will need to continue developing before they are able to successfully function outside of your womb.
Baby’s head takes up about half the length of their entire body, with a pretty pronounced bulge in the front. The bulge will eventually be filled with baby’s growing brain and their head will become more proportional to the rest of the body sometime in the third trimester.
Bones and cartilage are beginning to form in baby’s limbs and digits, giving them less of a nub or paddle-like appearance. Baby will also lose the webbing of their fingers and toes this week. By the end of this week, you can expect baby’s limbs to be fully formed and functional.

10 weeks pregnant ultrasound
There are a few reasons why you might be receiving an ultrasound at 10 weeks pregnant. If you haven’t yet had an ultrasound to confirm your pregnancy and verify your dating, then this would be one big reason.
10 weeks gestation is also the earliest some genetic testing can be performed. More commonly performed between 11 and 13 weeks, the nuchal translucency screening can be done as early as 10 weeks.
If you have an ultrasound done at 10 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.
Why is week 10 of pregnancy the worst?
Early pregnancy symptoms tend to be at their peak around weeks 9 and 10, making these weeks of pregnancy the worst for some women. What is the reason for this? HCG levels are thought to be the highest around week 10, and there tends to be a direct correlation between hCG levels and those pesky first trimester symptoms.
Rest assured that your morning sickness, and hopefully many of the other early pregnancy symptoms, will begin to fade when hCG levels start dropping around 11 or 12 weeks.
You might find that sleep is harder to come by too, another reason why week 10 of pregnancy is so unpleasant. The fluctuations in hormones, coupled with urinary frequency can really throw a wrench in your sleep and wake cycles.
10 weeks pregnant is how many months?
Curious how many months along you are at 10 weeks pregnant? Even though you are going to hear pregnancy discussed in weeks the majority of time, if you are wondering about how many months you are at 10 weeks, the answer is three!
