Thanks in advance for any and all help.

I got my period Friday, it wasn't due til this wednesday. It was super light for the first two days then normal on Sunday. Not heavy but enough for a pad. My periods are pretty regular 28 day cycles. Today I am still spotting but just barely,only when i wipe. My periods are exactly 7 days. Every month.

I don't believe I am pregnant. My husband and I don't use condoms but he does pull out. Sorry i know, TMi.

Also, I don't normally cramp much or at all during a period. This time I was crampy. My back was hurting also.

Has anyone had this before?? If so, what could cause your period to go out of whack like that?
