I had a period last month (June) on the 6th, and I had unprotected sex a day or two after it was over. I took Plan B before 72 hours were over, and I had another period on June 20th. Calculating from that period, and my normal 28 day cycle, I was supposed to come on around the 17th of July. It is now July 25th, and I still have not had a period. I've been getting all the normal period symptoms, like the bloating, the cramps, and everything else that comes along with my month visitor. I've also been feeling like I'm having a lot of discharge, but still there is no period. I'm pretty sure I wasn't ovulating at the time of unprotected sex, but since I'm more than a week late, I'm starting to get REALLY paranoid! I don't know if this is just a side effect of Plan B, or what is going on, but I'm starting to get really afraid! Help please!
