Hi, I was recently diagnosed with pcos. We have been trying to conceive for 9 months now. I was put on metformin and I had my last period on the 23rd, after 3 weeks of being on it I started my period on the 13th again. Has anyone had any experience with this. Just wondering if I stay on it if all my periods will be 3 weeks apart or if it’s just trying to regulate my period and hopefully in a month or two I will be on a “normal” 28 day or so cycle length. ( my cycle length used to be 72-102 days).
