Ok so one week before my period was due I had a couple days of brown discharge then it went pink, bright red then brown. It had along with it headaches, dizzyness, cramping in abdomin and back, and mood swings. It lasted a week in total and my normal period last 3-4 days. Now since I'm on the pill I missed a couple of days taking it and thought it could be breakthrough bleeding but I missed pills two months ago and had breakthrough bleeding and my actual period. 3 days before due period I took a hpt and was negative. Any positive info? Btw having unprotected sex as well.
