9 Weeks Pregnant: Week-by-Week Guide

9 Weeks Pregnant: Week-by-Week Guide

Congratulations! You’re 9 weeks pregnant and have now entered the last month of your first trimester. Check out this week-by-week guide to find out what’s in store for your baby and your body in week 9 of pregnancy.

  • 9 weeks pregnant is which trimester? First trimester
  • How many weeks of pregnancy are left? 31 weeks
  • 9 weeks pregnant is how many months? You’re in your third month. 

With week 8 of your pregnancy complete, you’re on week 9. Enjoy it, as week 10 is on the horizon! 

One of the most exciting things about pregnancy is how many changes you’ll experience with your little one over the span of just seven days! Here are some tips and tricks to keep on top of all that’s happening.

Your baby at 9 weeks pregnant

What’s happening in there

  • Your baby is the size of a cherry.
  • You’re officially in the last four weeks of your first trimester.
  • The countdown continues: You've got 31 weeks to go!

9 weeks: baby development 

  • A baby baby: Wondering what your baby looks like at 9 weeks? Your little one is now about three-quarters of an inch long and weighs one-tenth of an ounce. They will soon be making the transition from an embryo to a fetus.
  • Tiny tummy: Baby’s digestive tract and anus have formed, but they won’t be producing waste for quite a while.
  • Heads or tails: As your baby’s face becomes more pronounced, the tiny tail-like tip of the spinal cord has shrunk considerably and will almost disappear by the end of this week.
  • Baby's working hard: The little heart in there is now beating 150 times a minute, or nearly double your heart rate.
  • Bend and flex: Baby’s bones and tiny muscles are growing, with development between the brain and nerves, meaning the elbow can bend this week.

What should I be feeling at 9 weeks pregnant?

  • There are mood swings, morning sickness, fatigue, and weird cravings—but rest assured, you’re doing great. And you’ll be hearing your baby’s heartbeat very soon!
  • You may notice the appearance of red or blue spider (or varicose) veins in your legs. Try to avoid doing things that restrict blood flow, like crossing your ankles or legs or wearing tight socks.
  • Food aversion is when something you’d normally love holds no appeal, or even the thought of it makes you feel ill. Luckily, it won’t last forever. You may also be experiencing some unusual pregnancy cravings.

Can you feel the baby move at 9 weeks?

It’s still early. Your little one may be moving, but you’ll probably start feeling those wondrous flutters, known as “quickening,” around week 16.

Week 9 pregnancy symptoms

During week 9 of pregnancy, your body is changing quickly. As your baby grows, you will too, and there are certain pregnancy symptoms you may experience at this time.

10 common week 9 pregnancy symptoms

  1. You're still experiencing mood swings. This is totally normal given how your hormones are surging.
  2. You’ll be very fatigued at points as your body draws in nutrients to feed your little one.
  3. You will feel like you have to pee all the time, but at the same time, you need plenty of fluids to stay hydrated—just avoid too much coffee.
  4. If you’re getting headaches, it may be from hormones or your body adjusting to changes in posture. You can still take acetaminophen if you already do.
  5. You may still be feeling nauseous from morning sickness. Soothe your pregnant stomach by trying foods that contain ginger, ginger ale, or ginger lollipops. Also, consume foods that are bland and low in fat.
  6. You may start to experience back pain at 9 weeks pregnant.
  7. Increased blood flow and your growing baby putting pressure on blood vessels may cause varicose veins.  
  8. Your breasts at 9 weeks pregnant may have visible blue veins due to increased blood flow and growth in anticipation of your baby’s arrival.
  9. Heartburn, courtesy of increased progesterone production, is a frequent symptom. 
  10. At 9 weeks pregnant, discharge may increase and can continue throughout your pregnancy.

Can 9 week pregnancy symptoms come and go?

Some moms-to-be experience every symptom under the sun, while others have just a few. Every woman is different. And as hormone levels fluctuate, so can your symptoms. Some symptoms may disappear or change as your pregnancy progresses. Speak with your doctor to alleviate any concerns.

Can you start showing at 9 weeks pregnant?

Do you find yourself staring at your pregnant belly in front of the mirror, trying to spot a bump? As you reach the ninth week of pregnancy, your waist may be thickening, but you may also not look pregnant at all yet, especially if this is your first baby

3 tips for week 9 for a healthy and safe pregnancy

Being 9 weeks pregnant is an important time for you and your baby. Here are some tips on how to adjust to this new stage to keep you and your baby safe.

  • Love at first sight: You will be coming in for your first prenatal appointment. There will be a range of tests, but there’s also the excitement of hearing your baby’s heartbeat for the first time.
  • Is that safe: Educate yourself on what’s safe to eat and do when you’re pregnant. It will surprise you, like not handling cat litter or having to change to cosmetics that are pregnancy-friendly.
  • Burn baby burn: Heartburn is a part of pregnancy for most women at some stage due to hormones. Avoid heartburn triggers, such as acidic or spicy foods, carbonated beverages, and fried foods.
