Here’s what to expect when you are 7 weeks pregnant with twins:
By 7 weeks in the twin pregnancy, each of your twins will be about 0.5 inches long (13 mm) from crown to rump. Each baby is about the size of a blueberry.
Your twins’ hearts are starting to pump blood through the body and their livers are producing blood cells.
What to Expect
Some symptoms at this stage include clothes starting to get tight and frequent trips to the bathroom.
