I've had a myomectomy in 2008. I've had ultrasounds and scans that currently show absence of fibroids. I'm negative for PCOS as well. I've had issues with my periods since after the surgery with my periods returning to normal, to heavy with clots and then going haywire again. I was placed on Provera tabs for three months. My periods returned to normal for a moth after the Provera treatment, but now, I've not had a period for two months. What else could be wrong?
