I should of started my period 6/13-6/15 somewhere along those days. I have yet to start this month. I have some abdominal discomfort at times but AF has not showed. I took a pregnancy test 6/16 and it was negative. I have been trying to get pregnant since November 2013 so I'm wondering if this could be it. I have never missed a period, its actually normally spotting prior to cramping and last 7-10 days. I have not had this at all. Anyone have an idea what could be going on. Thanks!
