How long can I cheerlead while i'm pregnant?

Probably 12 weeks.. I know fitness and aerobics instructors who were pregnant. Their docs had them stop anything high impact around the beginning of teh second trimester. The baby is below your pelvic bone before then and very protected even from blows to the stomach. Also, a miscarriage in teh first trimester will usually just happen because, not because of the activities or actions of the mother. Also the more in shape you are, the longer you can do athletic things, but anything dangerous to the fetus (such as cheerleading) would need ot stop around 12-13 weeks.
