I'm 21 and in college. Periods are very regular, 28 day cycle and it never fails. I always have extremely bad cramps also. This month I started and entire week early. My breast were full and a little tender, which I don't experience on my period and I had very little cramps. But I have been cramping for a week before I started this cycle. I just was wondering if it was possible. I have taken a test but it came back negative, I could have just been to early to tell?

Have you had unprotected (or even protected) sex?
