9 Weeks pregnant: Symptoms, baby development and more

Now that you’re 9 weeks pregnant, you’re probably starting to think about how life will change when baby is in the picture. That’s why around week 9 of pregnancy, you might want to start looking for ways you and your partner can budget so you have extra cash when baby arrives. You should also consider checking out your company’s handbook to see how maternity leave is typically handled. That way, when you break the news to your boss, you’ll be prepared to discuss your expectations—and begin a potential maternity leave plan.

How Big Is Baby at 9 Weeks?

Baby is the size of a cherry at 9 weeks pregnant. Your 9-week fetus measures around 0.9 inches and weighs about 0.07 ounces, and their growth is picking up steam!

9 Weeks Pregnant Is How Many Months?

Doctors generally track pregnancy by week, not month—but if you’re dying to know how many months pregnant you are, at 9 weeks you’re entering your third month of pregnancy. Just a few more weeks to go in the first trimester!



Right now, the pregnancy hormone hCG is circulating through your body at its peak level. That means at 9 weeks, some pregnancy symptoms may be at their most severe. Hang in there—you’re just weeks away from those hormones leveling out a bit, leaving you feeling a lot more like yourself. Here’s what 9 weeks pregnant symptoms you may be experiencing:

  • Mood swings. Because those hormones just keep raging, and also because other symptoms—such as nausea and fatigue—are bothering you, you may find your emotions more difficult to control. It’s okay to slow your usual pace, to take breaks (to nap, to meditate or just to veg out and binge-watch Netflix) and to avoid stressful situations for the sake of your sanity.
  • Morning sickness. Up to 80 percent of pregnant women experience some form of morning sickness. It really should be called all-day sickness, though! If you’re suffering from nausea, you might just be feeling a little ill, or you may be vomiting regularly. If you are 9 weeks pregnant with twins, you may find yourself with more severe morning sickness symptoms. The good and bad news is that at 9 weeks, morning sickness is likely at its worst. Do some trial and error to see what makes you feel better—many moms-to-be find that ginger, frequent meals and snacks, and vitamin B6 help ease nausea. You’re suffering now, but this too shall pass. You can get through this!
  • Frequent urination. Because your uterus is expanding and because there’s major blood flow to your pelvic area, you may be heading to the bathroom more often than you did pre-pregnancy. Don’t let that stop you from drinking lots of water. It’s important that you stay hydrated. Just put more pit stops onto your mental to-do list.
  • Fatigue. While your hormones are working overtime to grow and develop your 9-week fetus, you might be feeling totally zapped. Sleep more, if you can, and expect to need to eat more (healthy) snacks; most pregnant women can’t tolerate skipping meals, even if they did it all the time before pregnancy. In the second trimester, you’ll get some of your energy back.
  • Nasal congestion. Surprise! Pregnancy can cause higher mucus production in the body—an unexpected symptom—so you might need to keep tissues handy.
  • Headaches. Thanks again, hormones! Those surges can give you headaches—and so can dehydration, caffeine withdrawal, hunger, lack of sleep and stress. Deal by treating your other symptoms, eating at least every few hours, getting plenty of sleep and drinking lots of water. A warm or cold compress can ease a headache and so can rest. Before you take any medication, clear it with your doctor. Many say acetaminophen (Tylenol) is okay but naproxen and ibuprofen (Advil and Motrin) aren’t. It will depend on your health history and any other medications you may be taking.


The first prenatal appointment typically happens between weeks 8 and 12. So by now, you may have visited the OB—if not, you will soon! At that first appointment you may even see baby’s tiny heartbeat on the ultrasound. Exciting stuff, huh?

Week 9 ultrasound

A 9 weeks pregnant, ultrasound is typically done transvaginally. That means the doctor or ultrasound technician will have to insert a probe into your vagina, since your uterus still sits behind your pelvic bone. (Don’t worry—it doesn’t hurt!) The probe will emit sound waves, which will allow you to see an image of your 9-week fetus on a screen.

Not only will you catch a glimpse of baby—who will resemble a lima bean—but the 9 weeks pregnant ultrasound will also confirm that the pregnancy is uterine (which means there are no signs of ectopic or tubular pregnancy at 9 weeks). The doctor may point out the gestational sac, the yolk sac and the fetal pole.

Inside your week 9 pregnant belly, baby’s working on that cuteness, developing more distinct facial features. And baby might now have a strong enough heartbeat to be picked up by a fetal doppler.

At 9 weeks pregnant, miscarriage risk is on a lot of women’s minds. Rest assured that once you’ve seen or heard a heartbeat, the risk dips to 2 to 9 percent, depending on your age, and will continue to lower in the coming weeks.

Other prenatal tests you can expect around 9 weeks pregnant may include blood work to test for hormone levels, blood type, white and red blood cell counts and certain STDs. You may also have a pap smear to check for abnormalities (which can be signs of cervical cancer), and a urine test to screen for UTIs and check that the protein levels seem healthy. All that poking and prodding will totally be worth it when you’re holding your newborn baby. All in good time!
