This is my third child. I have never had Braxtonhix contractions before, and was induced with both my previous pregnancies. Off and on for the last week I've been having cramps that are like period cramps in my lower abdomen and back. However, for the last 24 hours I've been having what feels like really bad period cramps. Sometime I feel like I need to use the bathroom, but I can't. They are so painful they are waking me up,and it even feels/looks like my stomach is smaller during them. I've also be feeling very sick to my stomach and feeling a pinching/stabbing sensation in my vagina. Has anyone ever experienced this?
