For the past two days I’ve had menstrual like cramps but they began to get worse last night, I’ve also been experiencing really bad back pain, and I am indeed contracting. My stomach at times is tender to touch and I’ve had this horrible burning sensation below my left side of my ribs. I’m super nauseated today and have had diarrhea as well. I’ve been up all night unable to sleep from being so uncomfortable. Should I go in and get checked out or wait it out? I’m 39 and a half weeks.
