So have any of you ladies with PCOS been prescribed metformin and it regulate your period? I’m asking because I have been on metformin and had regular periods for a long time but I was put on letrozole 7.5mg days 3-7 yet I’m on cd 17 and still no positive opks or any other sign of ovulation. Have any of you experienced this? I’m loosing hope. Can I still have regular periods with no ovulation?
