Ok so I just started taking Metformin 4 days AFTER AF ended. This would be cycle day 9. On cycle day 11, 12 i had ewcm. Which seemed to be earlier than usual. I usual ovulate cycle day 15,16. Well the OPKS are negative. I have a regular cycle I was prescribe Metformin to manage my weight due to PCOS. I have been trying to conceive for 5 months now so this has thrown me all the way off with tracking. Did I ovulate early because of the Metformin? Does it work that fast? Even though I ovulate regularly without it I think I may have ovulated earlier. Keep in mind I would have only taken Metformin for two days before ovulating if that’s the case
