Falling into place with metformin ? 🙏🏽👶🏽

I started metformin August 10 , I'd say we've been trying to convince about 10-12 months and nothing I had supper irregular periods like every 90 days sometimes they'd come and sometimes not , two weeks or more of heavy bleeding and *TMI* huge Blood Clots , but I started metformin and I had a period on September 2nd and ended on September 7th 😱 I was like what !!?? 6 days 😁 and I was scared at first that it wasn't working because my period was pretty heavy the first 3 days and all I could say was that it was going to be a long month 😏 but it's over like really over now just how do I know if I'm ovulating ? I'd really like to be a mommy now I'm 20 years old by the way 💁🏽 , diagnosed with PCOS 8/10 , because I gained to much weight to fast , about 70 pounds from being on birth control  (depo shot ) I got the shot twice , which is 6 months and in that 6 months I gained 50 pounds ! And the weight just started adding up from there 😓 but I'm on my journey back to being myself and trying for baby #1 💜
