Bladder/uterus pain with Prednisone?

Victoria

So two days ago my doctor put me on Prednisone for a sinus infection. Today I woke up to extreme pain around my bladder/uterus area. It almost feels like gas but it won't go away and I'm starting to get scared. I'm not pregnant or anything. My period isn't for another two weeks or so. Peeing doesnt hurt or anything. I'm just in a lot of pain and I don't know what to do. Could the prednisone do this?
