Pregnancy after miscarriage

I had a miscarriage on March 13th and since then I've been put on Metformin to help regulate my periods. I have had one normal period since then, last month. I use this to track ovulation and while I know you need to have more than one cycle to know when ovulation occurs, I went by what the app told me and have been trying to conceive. Does anyone have any success stories on Metformin after a miscarriage?
