I started taking provera to start a period somewhere around cd 80 of my last cycle. I was prescribed 14 days of it and started bleeding on the 12th day (I did finish them though). I bled for 9 days, 4 of them were heavy with lots of clots. Then, 7 days later, I started bleeding again. I have long cycles, not short ones...sometimes I'll spot a lil in between periods, but I've never actually started bleeding again less than 3 weeks after the last period ended. Usually it's more like a month and a half or more later. Has anybody else had this happen? Should I call my doctor?
