Fundal Height For Twins?

What does it mean if I'm measuring too small or too big at the doctor's office?

When you visit your OB after 20 weeks, she may measure the distance from your pubic bone to the top of your uterus, which is known as the fundal height. Moms expecting singletons are measured regularly, but many docs won’t even measure women pregnant with multiples. Unfortunately, when you’re having twins or more, it’s more difficult to assess “average” fundal height. However, as long as you are gaining weight consistently and sufficiently and your fundal height is growing steadily, your doc will likely be satisfied.

If your OB does measure you and says that you are too big or too small, she will schedule you for an ultrasound to check things out.
