buying meds online?

I will try n make this as short as I can. Ob put me on clomid for two months, no responce so we switched to letrozole. Responce first month but not second, this is the third. I was told this would be my last script bc they only do 5 b4 refering to an RE. This usnt posible for us. The closest it almost 2 hours away( who we seen b4, but concieved our son naturaly jst b4 invetro) with my husbands job now traveling for assistance jst cant be done. So my hubby found a site online to get my same mexs from plus some at home testing kits to check for progesterone( ovulation reassurance) what do you think? Would you buy your meds online? Im desperate, but nervouse.
