Hi ladies! I am 32 weeks and a FTM. Lately at night mostly I have been having a crampy belly. All over my belly is crampy. Yesterday this happened all morning. It's not painful, I'm just worried. I don't think this is Braxton hicks? I am not sure though because I've never been through this before. Is this common? My next doctors apt is November 3. Any thoughts?
