The day after my period ended, I had protected sex. I was still worried so I purchased Plan B. After taking it, none of the side effects listed occurred. I felt normal. 5 days after taking Plan B, I got a browinsh discharge and had stomach cramping (it just felt like it always does when I first get my period) The next day, I have a mix of brownish/red discharge (along with a bright red when I wipe, which I find similar to when I have my period.) I take medications that have been known to alter hormone levels in some cases, I'm not sure if that and the Plan B are really messing me up? Is this normal? I read about a discharge you get when you become pregnant, is that happening? I'm a little worried but mostly confused and any clarification would be wonderful.
