PCOS and METFORMIN??????!

PCOS and METFORMIN??????

I am experiencing infertility, my husband and i have been trying for a baby now for a little over a year with no luck, i decided to go and see an infertility specialist whom after two visits diagnosed me with PCOS.
I thought it wasn't possible i had no symptoms other than the infertility and absense of periods.. But i did, he had done some blood tests which revealed that i have elevated testosterone levels and high estrogen, everything else was great meaning my LH, FSH, Glucose was good, He told me he would like to put me on Metformin, i heard it can restore ovulation and improve chances of conception, possibly decrease my chances of having miscarriages (have had 3 losses so far, all in between 3-5 months along)..Anyways he told me he wanted to do an HSG and a Hysteroscopy befor going ahead with the medication, the only problem is i cannot afford those procedures at the moment..I know you can get metformin online but when and how should i use it? when in my cycles? please help!

Note; i do not have any of the typical symptoms, if anything i'm a bit underweight (5'2, 107lbs), i have no facial/body hair, no acne.....Only elevated testosterone..I'm afraid that if i take the metformin it will make me loose even more weight?
I have been trying to gain weight but no matter what i do, how i eat i cannot gain weight but i loose it no problem, i go a day without eating and i'v already lost 2 pounds!

I have PCOS and my doctor prescribed metformin to me as well. I started out taking 1 tablet 500mg a day for a week then upping it to twice a day the second week. Its pretty hard on your stomach so I suggest the XR version. As for the tests you have to be honest with the doctor and tell him that you can't afford it. I didn't have any other tests aside from bloodwork when I was put on it. At the end of July my doctor is combining clomid and metformin since we are trying to conceive
