I took a Plan B pill on Dec 5th, 09, then bought and took another one the next day. I've been bleeding, like a normal flow, since Jan. 1st, going on 31 days. Is this a side effect from the Plan B pills? I know it can mess up your cycle, but I didn't think it would make it this bad.. Whens the bleeding going to stop? This is very frustrating. Help Please. :confused:
