AF was due on the 23rd of this month. Still nothing. Have had headaches, nausea, left pelvic pain and starting to have sore niples.. (tmi sorry) My husband and I have been sexual active, a few times with protection a few without. I bought a test but haven't taken it yet.. kinda scared that it might be positive.. I miscarried just last month.. is it possible to be pregnant again so soon. Or do miscarriages sometime affect AF??? Help!
