So I had my tubal done during my c section in August ,2017. I have never missed a period. Until now. I took a test it was negative. Their is a high chance I could be pregnant since my so and I have sex around the time I was suppose to ovulate. The only real symptoms to pregnancy I have is full bladder feeling I cramp like I’m gonna start. My nipples are sensitive and I am nauseous all the time all day long. I just don’t know what to do since I’m not getting a positive test yet. I’m also gonna call my dr first thing in the morning but has anyone else had this experience how did it turn out?!? I’m also 22 so I don’t believe this is the start of the early menopause that your supposed to get when getting your tubes tied.
