I am 7 mos pregnant with twins and i have pain right in front of my pubic bone. is this normal?

Yes: Yes, there is a fused joint there called the symphysis pubis. In pregnancy this joint loosens slightly to help make room for the baby to come through. With twins there is extra weight pressing down, putting extra tension on the joint. Other than waiting until delivery, there are things you can do to manage. You may want to try acupuncture, and find a chiropractor skilled in webster technique.

Pubic bone pain: At seven months of pregnancy, and beyond, the cartilage which connects the two branches of the pubic bone softens, and the two non-stable ends rub together when walking or getting up and down from a chair. This is normal, but can be very uncomfortable.
