I'm 40 weeks 2 days and I woke up and had to go to the bathroom REALLY bad (#1 ) took me a while to get #2 out but it finally came (just a little) then I got in a warm bath because I was still cramping..while I was in the bath I got this HORRIBLE cramp like I had to go again and I tried but I couldn't go...now this really really bad cramp keeps coming and going, and sometimes I have to rush to the bathroom thinking I have to go but I don't? My back is hurting too...like idk what's happening...
