@ange1111 correct silent endo which is without any symptoms at all.. I only ever had AF cramps on day 1, no pain with BD... With the PCO I actually don't have any cysts (had ultrasounds + lap no mention of PCO), I've always had sky high AMH (first sign) but I got O tracked via BT last month & realised my LH got to as high as 111 before I O'd..! 50 is considered a surge! So I asked for a day 3 FSH:LH BT & my LH was 80! FSH was ok but a ratio of >1:1.5 is problematic, my ratio was 1:13! High LH fries the eggies & make uterine lining unreceptive I think I just have the PCO morphology so my hormones are out of whack.. Yep on metformin now, it's meant to regulate the axis that produces those hormones starting with pancreas I think..
