It has been 112 days since my last period. I have taken a few hpt's, but they came up negative. I have this sharp pain in my pelvic area sometimes when I stand up. I have no diseases or std's. I have not recently come off the pill. I'm just wondering what could be going on. I'm going to the dr. This week.I just thought I would get some opinions. I am trying to conceive. Thanks !
