8 Weeks Pregnant with Twins

Joe Rawlinson by Joe Rawlinson - Last updated October 16, 2019

Here’s what to expect when you are 8 weeks pregnant with twins:

Fetal Development

By 8 weeks in the twin pregnancy each of your twins will be about 0.63 inches long (16 mm) from crown to rump. Each baby is about the size of a kidney bean.

Your twins’ yoke sacs are disappearing and they are starting to draw nutrients from the placenta via the umbilical cord.

What to Expect

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

Some symptoms at this stage include lower back pain, food cravings or aversions, and morning sickness.

Dad’s Thoughts

You’re still so early in the pregnancy that your biggest concern is avoiding miscarriage. This is only overshadowed by your shock that you will be having twins. Do what you can to help your wife ease the morning sickness that she’s been having for weeks.
