I normally have a 30-31 day cycle. I bleed about three to four days of a moderate amount in a dark red and brown color. I normally have horrible bloating and cramps (to the point of medication) for the week and some months, a week and a half, prior to AF. I engage in relations regularly. I did lose my bc pack and missed a day halfway through the cycle. I took two the next day. My period came two days early. It was only spotting (bright red) for a day and a half and then nothing. I had no bloating or cramps until AFTER I spotted. My real period was due yesterday and AF hasn't appeared yet. What could be going on???
