So I've been on birth control pills (Alesse) for about two weeks now. I started my pack about 18 days after I finished my last period. I got my period this morning (May 3rd) and have light cramps, and I'm not supposed to get it until next Wednesday (may 11th). I've been taking all my pills on time. And also was on this same brand of birth control for a year before now (went off of it for 4 months). So my question, is it normal for this to happen? Thanks.
