Help!!! 31 weeks 1 day. Third pregnancy. Had some Braxton hicks contractions last night, worried me enough to call my dr. She said drink a few big glasses of water and lay down. It worked tremendously and I've had only a few throughout the day today. But about 2 I had to use bathroom and I have some bad diarrhea. Wouldn't worry me except I've had constipation issues my whole pregnancy. I've gone five days not being able to go. It wasn't the runs when I started to use bathroom but ended that way and I've been back twice now. Should I be concerned??!?help
