10 Weeks Pregnant: Symptoms and More

Hello baby bump! Now that you’ve reached 10 weeks pregnant, you may stop wondering when you’ll start to actually look pregnant, because it’s probably right around now! That’s why week 10 is a good time for a little retail therapy. While you shop, stock up on some new, looser clothes—and maybe your first round of maternity wear. Don’t go too crazy at the store though. As your body continues to change, you’ll want to pick up some more essentials along the way. Remember, you’ve still got many more weeks of body changes ahead.

This week, you and baby have made a big accomplishment: baby is no longer an embryo—now baby is officially a fetus. That means they’re becoming more and more baby-like, and you’re inching closer and closer to leaving the nasties of the first trimester behind you.

How Big Is Baby at 10 Weeks?

During week 10 of pregnancy, baby is as big as a strawberry, measuring about 1.2 inches long and weighing about .14 ounces. Your 10-week baby’s body length will almost double in the next three weeks. Wow!

10 Weeks Pregnant Is How Many Months?

At 10 weeks pregnant, you’re about three months and one week pregnant—but remember, most doctors prefer to track pregnancy by week, not by month. That’s because pregnancy is 40 weeks long, which means your due date comes at the end of your 9th month!

Week 10..


Wondering what to expect at 10 weeks pregnant? As baby grows, your ligaments and muscles are starting to stretch inside your 10 weeks pregnant belly, your breasts are getting bigger and some other radical changes may be happening. Here are some of the most common 10 weeks pregnant symptoms:

  • Round ligament pain. Don’t be surprised if you start feeling some aches and pains in your abdomen as it stretches to accommodate your growing baby. While some moms-to-be don’t really get or notice them, others find these sensations—called “round ligament pain”—well, downright painful. If you’re 10 weeks pregnant with twins, round ligament pain could be even more noticeable. Let your OB know if your discomfort is intense or if you’re worried in any way about your 10 weeks pregnant symptoms.
  • Growing breasts. Your breasts have probably gotten bigger by week 10 of pregnancy, since they’ve been prepping for breastfeeding for weeks already!
  • Morning sickness. Nausea and vomiting are pretty common at 10 weeks pregnant. The good news is, they’ll likely subside soon after you hit the second trimester.
  • Mood swings. Changes in your hormones may be to blame for a roller coaster of emotions.
  • Fatigue. You’re zapped. Here’s why: Not only is your body working really hard to grow baby, but your sleep might be disrupted by some pretty weird dreams.
  • Increased vaginal discharge. An increased blood flow to your vagina coupled with an increase in estrogen production could cause more of a clear, odorless discharge called leukorrhea. It might seem a little gross, but this substance is simply nature’s way of getting rid of bacteria. If it’s colored, tinged with blood, has a foul odor or causes discomfort, however, call your doctor. Those could be signs of something else.
  • Visible veins. Those blue streaks are an important reminder: They’re a sign of all the extra blood circulating in your body for your growing baby!


Your 10 weeks pregnant belly is probably just starting to show. That’s because your baby is continuing their rapid growth and so your tummy has started to develop some extra curve. You still might not look pregnant to people you meet, but you might need some pants with a stretchy waistband and some loose-fitting tops right around 10 weeks pregnant.

Many doctors recommend gaining about one to five pounds during the first trimester for pregnant women of normal BMI. So you’re right on track if you find yourself having gained a few pounds at 10 weeks pregnant.

If you’re pregnant with twins, your doctor may recommend you gain about a pound per week in the first half of your pregnancy, which means you could have gained about 10 pounds by the time you’ve reached 10 weeks pregnant with twins. But don’t worry if you haven’t gained that much weight, or even if you’ve lost weight due to morning sickness. You’ll hopefully be able to put weight back on during the second trimester when the nausea decreases.


Week 10 of pregnancy is a milestone: Baby is no longer an embryo—they’re now a fetus! These two terms simply define different phases of development. The embryonic phase is about forming major organs, including the brain, heart, and lungs, plus the arms and legs. Once you’ve got a fetus, those organs and parts are formed and are now growing and developing.

At 10 weeks pregnant, baby has working arm joints, and cartilage and bones are forming. Fingernails and hair are starting to appear too! And can you believe baby is busy practicing swallowing and kicking inside your 10 weeks pregnant belly?

Ten weeks is an important time if you’ve decided to have some first trimester genetic testing. Genetic testing is optional; which ones you choose to get—or not get—is up to you, but a genetic counselor can help you decide based on your family history and risk factors.

The nuchal translucency screening (a.k.a. NT Scan) typically happens between weeks 10 and 14; it tests your fetus for risk of Down syndrome and several other chromosomal abnormalities. For it, you’ll have a painless ultrasound, and baby’s nuchal fold (back of the neck) will be measured for signs of abnormality. The NTS is typically done as part of a “First Trimester Screen” where your blood is tested and your risk is assessed based on the results of both the ultrasound and the blood test.

A cell-free fetal DNA test, also known as a non-invasive prenatal test (NIPT), is a blood test drawn at week 10 or later. It screens mom’s blood for signs of risk for Down syndrome, Edward Syndrome, Patau Syndrome and other chromosomal abnormalities.

Other, more invasive tests—the CVS and amniocentesis—can be used to diagnose abnormalities as well. They’re typically performed if you have a higher risk of having a baby with a chromosomal abnormality, whether based on family history, risk factors or NTS or NIPT results.

The CVS (chorionic villus sampling), performed between weeks 10 and 13, uses an ultrasound to determine the placenta’s location. Then, using ultrasound as a guide, the doctor inserts a needle through your belly or through the vagina while doing a speculum exam to collect cells from the placenta. Those cells are tested for genetic abnormalities.

If you opt for amniocentesis, you’ll schedule it for between weeks 15 and 20. Overwhelmed by all the first- and second-trimester testing? Trust us; once you’re done with it, you’ll be able to concentrate on more fun to-dos.


Reminders for the week:

  • Schedule your CVS test (if you’re opting for one)
  • Schedule your nuchal translucency screening
  • Get the downlow on exercise dos & dont’s
