I am supposed to get my period on February 7. For the last week or so I've been having severe cramping, lower back pain and random jolts of stabbing pain my abdomen. On the 30th, I began bleeding VERY heavily. I continued bleeding all through the day Wednesday and all day Thursday, all really heavy. Today I woke up and the bleeding has completely stopped. I'm still feeling some mild cramping but nothing too severe. What could this be? I'm 22 years old and I haven't been on birth control pills since October. I've always had a regular 28 day cycle (almost to the day every month)... My fiance and I use condoms every time.
