What Week 20 of Your Pregnancy is Really Like

Mom's changing body

This week is a cause for celebration—you've reached the halfway point of your pregnancy! If you turn to the side these days, others will really notice a change in your profile—you definitely look pregnant now. If you haven't felt round ligament pains yet, you may soon. These sharp pains in your hip, abdomen or groin are normal. As your uterus grows, the round ligaments, which are attached to your pelvic sidewall and each side of your upper uterus, are pulled and stretched.

Weekly Tip

Wacky, scary, vivid, and unsettling dreams are all totally normal during pregnancy. These dreams may be spurred by anxieties you have about motherhood or labor, along with insomnia, or trouble falling asleep. You can let your imagination run wild with these nightmares... or you can take a deep breath when you wake up and talk about your dreams with your partner or friends. If you rationalize your fears as they're surfacing in your subconscious, you can let go of some of your worries.
