11 Weeks Pregnant with Twins

Here’s what to expect when you are 11 weeks pregnant with twins and nearing the end of the very first trimester:

Fetal Development

By 11 weeks in the twin pregnancy each of your twins will be about 1.6 inches long (41 mm) from crown to rump. Each baby is about the size of a fig or Brussels sprout.

Your twins’ fingers and toes have formed and they may even be sucking their thumb by now.

What to Expect

Typical weight gain for Mom at this point is between 1 to 1.5 pounds/week (0.5 to 0.7kg).

Total weight gain for the twin pregnancy so far will average between 11 to 17 pounds (5 to 7.7kg).

Hopefully, the morning sickness of the first trimester is easing up by this point. Typical symptoms at this stage include constipation, bloating, and gas.

Heartburn will likely be an issue during this stage and throughout the pregnancy.
