7 Weeks Pregnant: Week-by-Week Guide

    7 Weeks Pregnant: Week-by-Week Guide

    Congratulations! You are 7 weeks pregnant. At this stage of your journey, new developments are beginning to unfold. Explore Enfamil’s week-by-week guide to find out what’s in store for your baby and your body in week 7 of pregnancy.

    At 7 weeks pregnant:

    • Your baby is the size of a blueberry
    • You’re officially in 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 baby is from at 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.

    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 yourself repulsed by the aroma of foods that have traditionally been favorites.
    • By week 7, you’ll probably already 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 baby a safe space. Between the development of the placenta and the formation of a mucus plug in your cervix, your baby’s all cozy to grow. 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 7 of pregnancy, your body is adjusting to the new life it’s supporting. As your baby changes, you will too, and there are certain pregnancy symptoms you may experience at this time. Keep these week 7 pregnancy symptoms on your radar:

    • Your mouth is still producing excessive saliva you may even drool. Oops.
    • You’re also likely feeling like you need to pee constantly.
    • It’s not uncommon to have cramping in the first-trimester.
    • You may get some acne. The pregnancy hormones can cause your skin to break out.
    • You may still be getting morning sickness at week 7.
    • Your mood may be swinging, coupled with fatigue.


    Being 7 weeks pregnant is an important time for you and your baby. Get advice on how to adjust to this new stage from the experts at Enfamil.

    • 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 gets bigger.
    • 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 important vitamins, minerals, and nutrients, such as docosahexaenoic acid (DHA).
    • Check your makeup and medication to ensure it's safe for use during pregnancy.
