I'm a FTM at 33w2d. I thought I knew what BH Contractions felt like, but now I'm not so sure. I've had an occasional very light cramping feeling in my lower belly since 20 weeks. I assumed they were BH, but I recently started having this tightening feeling all over my stomach that lasts about 20-40 seconds then relaxes and tightens again a few minutes later. Its not very painful, it feels like the baby is pushing her body against my uterus and making it harden. Could that be BH Contractions?
