I toom Plan B the day after my last cycle ended, which was Nov 1st, so I took the pill Nov 2. I took the pill within an hour or so of the incident happening. About two or 3 days later I started bleeding, it was heavy enough to seem like another regular period, and it lasted for 4 days. My expected period date was originally Nov 25. It is now Nov 27 and I am starting to panic a little. I know that's a little overdramatic, and your period could be up to a week late after taking the pill, but I'm really scared. Any advice?
