9 Weeks Pregnant with Twins

Here’s what to expect when you are 9 weeks pregnant with twins:

Fetal Development

By 9 weeks in the twin pregnancy each of your twins will be about 0.9 inches long (23 mm) from crown to rump. Each baby is about the size of a grape.

Your twins’ heads are still disproportionately large compared to their bodies but their eyes are now moving from the side of the head to the front.

What to Expect

Typical weight gain for Mom at this point is about one pound per week.

Total weight gain for the twin pregnancy so far will average between 9 to 14 pounds (4 to 6.4 kg).

Mom may have headaches, mood swings, and continuing morning sickness.
