Help!

Been TTC for 3 years with no luck! Anyone on here gotten pregnant using natural remedies rather than medication with PCOS. I Tried fermara and metformin for 1 cycle and then moved and couldn’t get them anymore. Now i am ready to try again but I’ve heard and had close family experience bad side affects from using the medication, almost killing a family member and forcing to deliver their baby early. And causing birth defects in babies. If anyone has any tips on this please share with me.
