Highlights this week

Hair is sprouting

Hair is visible on your baby's head – and may grow like a weed or only slightly by the end of pregnancy.

Find the best baby monitors, nursing pillows, diaper bags, and wearable blankets to put on your registry.

Activities to avoid now

Hearing your heartbeat

Your baby may be able to hear sounds faintly from inside your body, such as your breathing, your heartbeat, and your digestion. These sounds will grow louder as your baby's hearing improves.

Hairy and wrinkly

If you could see inside your womb, you'd be able to spot the fine hair (lanugo) that covers his body and the deep wrinkles on his skin, which he'll sport until he adds a padding of fat to fill them in.

Pregnancy symptoms during week 22


Increased oil production may cause you to develop acne.

Stretch marks

You may start to notice stretch marks on your abdomen as it expands to accommodate your growing baby. These small streaks of differently textured skin can range from pink to dark brown (depending on your skin color). Although they most commonly appear on your tummy, stretch marks may also show up on your buttocks, thighs, hips, and breasts.

Start doing Kegel exercises

Kegels can help prevent urine leaks during and after pregnancy, keep hemorrhoids at bay, and improve the muscle tone of your vagina, making sex more enjoyable.

Think about your baby shower

Moms-to-be usually don't throw their own baby showers (a relative, friend, or coworker usually does this for you), but you can weigh in on the theme, games, and guest list.
