7 Weeks Pregnant: Week-by-Week Guide

Congratulations! At seven weeks pregnant, you’re well into your first trimester. There’s plenty of incredible developments happening at this stage of your journey. Check out this week-by-week guide to find out what’s in store for your baby and your body in week seven of pregnancy.

  • 7 weeks pregnant is which trimester? First trimester
  • How many weeks of pregnancy are left? 33 weeks
  • How many months is 7 weeks pregnant? You’re one month and three weeks pregnant.

With week six of your pregnancy complete, you’re on week seven. Enjoy it, as week eight 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.

What’s happening in there

  • Your baby is the size of a blueberry.
  • You’re officially into the second month.
  • The countdown continues: You've got 33 weeks to go!

What happens during the 7th week of pregnancy?

  • The connection is made: Baby’s umbilical cord is now connecting the embryo to the placenta, supplying oxygen and essential nutrients and removing waste.
  • Little duck feet: Right now, your baby’s hands and feet are webbed, with the fingers and toes yet to form.
  • 10,000 times the size: That’s how much bigger a baby is from the time of conception.
  • Ready for diapers: Well, not quite, but the kidneys have now started forming.
  • The nose knows: There’s a tiny pair of nostrils growing.
  • Getting technical: This early in the pregnancy, it’s inaccurate to refer to baby as a seven-week fetus. Technically, your little one is still considered an embryo.

What should I be feeling at 7 weeks pregnant?

  • The powerful pregnancy hormones estrogen and progesterone keep fueling a range of positive and some not-so-fun symptoms.
  • With the strange cravings for food, you may also find you dislike foods (and food aromas) that have traditionally been favorites.
  • By week seven, you may have grown a bra size. Switching to a maternity bra can provide some support and relief from the aches and growing pains as your breasts evolve into a food source.
  • You’ve made a safe space for your baby. Between the placenta development and the mucus plug formation in your cervix, your baby has a cozy home
  • Keep up your part by being good to your body with regular exercise, plenty of rest, and nutritious food.

Week 7 pregnancy symptoms

During week seven 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 7 pregnancy symptoms

  1. Your mouth is still producing excessive saliva, so you may find yourself drooling a bit. That’s OK!
  2. You’re also likely feeling like you need to pee constantly.
  3. You may also have diarrhea—yes, even more bathroom visits. Check with your doctor if you’re concerned about any gastrointestinal (GI) symptoms.
  4. It’s not uncommon to feel cramping in the first trimester.
  5. You may break out more often, thanks to pregnancy hormones.
  6. You may still be getting morning sickness at week seven.
  7. Your mood may be swinging, coupled with fatigue.
  8. You’ll crave certain foods, while you may have an aversion to others—possibly even some of your favorites.  
  9. Increased progesterone production during pregnancy slows down the digestion process, which can cause bloating, burping, flatulence, and constipation.  
  10. You probably won’t have a belly bump yet if you’re a first-time mama, but you may be showing if you’ve had previous pregnancies. 

3 tips for week 7 for a healthy and safe pregnancy

Being seven weeks pregnant is a significant 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.

  • Exercise do's-and-don'ts: Exercise is important at this stage, but it may be time to start reading up on what exercises you should and shouldn’t do as that tummy grows.
  • Your body's working crazy hard: Over the next three months, your baby will form 100 billion neurons (cells in the brain and nervous system that transmit information) at an astounding rate of 250,000 neurons every minute! That’s why it’s so important to eat healthfully and take a prenatal supplement to make sure you’re getting essential vitamins, minerals, and nutrients, such as docosahexaenoic acid (DHA).
  • Are your products pregnancy-safe?: Check your makeup and medication to ensure it's safe for use during pregnancy.
