Is Meprate Effective In Helping To Conceive?

Hi doctor, I am 29 years old trying to conceive for the past 8 months. I have thyroid and taking 75 mg thyronorm prescribed by my doctor. I had a miscarriage in jan 2010. I am 74kg of weight and since my last miscarriage. I am scared If I will ever be a mommy. Usually I have my periods regular, however nov 2010, I was consulting a doctor and she fist prescribed me F-Gam and to my husband M-Gam without any test performed. I took that tablet for 5-7 days and cud not find any information on net, so stopped taking it, when I asked doctor she said this is a substitute for folic acid tabs.Then she asked me to go for an abdomen scan, and she noted small cysts and prescribed me Lutroz for five days and Diana 35 for 21 days, the following month I had very light bleeding for only two days. upon asking my doctor, she told me that diana 35 causes less periods with less flow. and after she got tested my follicular study and she found that my egg size is not good, it was just 6-7 cm instead of 18-20cm on the 10th day and the ET is also not as expected, so to increase my egg size she injected 225 units of FSH, the egg size was increased a little with that however the ET was still a problem. so she prescribed me M2tone along with Ovacare forte (A+B). I was a little upset then I consulted another doctor, The new doctor asked to continue with ovacare and she did not say anything about M2tone and asked me to stop. and she asked me If I had my first pregnancy happened by itself. I said yes, it was by itself. Then she asked me to not to pressurise myself much and should try without medication except ovacare forte for next 6 months. Last month I missed my periods and the HPT after a week was negative. I did a beta pregnancy test which was also negative after 10 days. so she asked me to take meprate 10mg for 4days/twice a day after food and I finished with the meprate course today(13 july 2011). please advise If it good for me to conceive and anything else which can help me conceiving. Thanks
