I haven't had my period since last year in December but that was only because I had taken Plan B for an accident. Today marks my week since I've dealt with having to consume this pill yet again. GREAT! Yeah, I'm well aware this suggests I should just get on Birth Control. I'm working on it as we speak but my question to anyone who is willing to answer.. How will I ever know if Plan B worked if I never even had a period since then to help me determine when I should start, and will I get my period soon enough if I took the pill minutes after? I'm really not proud of myself having to ask someone to give me an answer on a mess up, but I'm human. Thanks to anyone who takes the time to give me an answer. <3
