Gas can cause really sharp pains. It would be my guess. Try the Benefiber.
yea i'll try that i'm not so sure that that's what's going on. these cramps aren't those dull painful cramps.. they're really sharp pains that last for a while throughout the day.
I would try two things: take potassium (or foods rich in potassium), because potassium is supposed to be good for addressing muscle cramps, and take a stool softener like Benefiber (very easy to take, no flavor or graininess) in case it might be something relating to gas (like, having the baby affected your intestines in some way). If neither thing has any effect, I would see a doctor.
