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