(TMI) I feel pain and pressure in my cervix and butt, mild menstrual cramps, lower back and thigh pain and like I was constipated but now I got diarrhea instead... Could these be signs of early labor? The symptoms have gotten a lot stronger during the last couple of days. I also have waves of nausea throughout the day. I'm 39 weeks pregnant tomorrow. I have a lot of Braxton hicks contractions and especially my lower belly feels very tight.
