Im not sure u should just take ur moms metformin mainly cause ur not sure what mg u should take etc.I dont see an infertility doc. I see a reg obgyn. She perscribed me metformin and provera wich induces my period. So if u can see ur obgyn and if they perscribe u metformin u can get it at walmart on the cheap list meds and at krogers. I got 90 metformin for 6.00 at walmart! so thats really good and cheap. I dont have insurance at all right now but I found a doc that works it all out with me. I only pay 29.00 a month till i get my bill caught up

Good luck hun! Hope this helps you! Take care <3
