Highlights this week

Hello, third trimester!

You'll most likely have a checkup every two weeks until 36 weeks, then switch to once-a-week visits until you deliver.

Starting the childcare search

If you're planning to return to work, start looking into childcare now, especially if you live somewhere good care is in high demand.

Comfy sleep positions

 “Side-sleep” and “almost-back sleeping” use pillows, towels, and blankets to support your back, neck, and growing belly.

28 weeks is how many months?

You're in your seventh month!

Baby development at 28 weeks

Brain boost

Your baby's brain is adding billions of new nerve cells. His senses of hearing, smell, and touch are developed and functional. During the third trimester, the brain triples in weight, and the cerebrum develops deep, convoluted grooves that provide extra surface area without taking up more room in the skull.

Nerve protection

A protective covering of myelin begins to form around his nerves during this trimester, a process that will continue for a year after he's born.

Pregnancy symptoms during week 28

Baby kicks

Your baby's very active now. Your healthcare provider may ask you to spend some time each day counting kicks and will give you specific instructions on how to do this.

Leg cramping

Leg cramps are more common at night but can also happen during the day. Your legs are carrying extra weight, and your expanding uterus is putting pressure on the veins that return blood from your legs to your heart as well as on the nerves leading from your trunk to your legs.

Nail changes

Some pregnant women develop harder nails, but others find that their nails are softer or more brittle.
