Quick question!! PCOS TTC

Carolina
Recently discovered I have PCOS. I noticed darker spots of skin and I got worried . so I looked it up and I discovered it was PCSOS. I know they prescribe Metformin to treat PCOS and I've heard many good stories about it. Now. I'm already on Metformin BC I'm pre- diabetic. But I had stopped taking them BC they were making me sick. (Normal) I had my birth control removed February and I've been trying for my #2 since . my question is.. I just started taking my metformin again the beingning of my AF this month !!! And I'll continue to take it daily as prescribed.. Have any of you experienced anything like this ? Any personal stories ?? Please !! ❤❤❤❤❤
