Talk to Gynecologist on Miscarriage

Hy I had 3 miscarriages. First two were weak beta hcg pregnancy and nothing was shown on ultrasound at time of bleeding and miscarriages occured spontaneous and 3rd pregnancy was only gestational sac pregnancy ended at 7 weeks with dnc. All miscarriages occur at 7weeks. I want to mention I was not aware that I had subclinical hypothyroidism during 3rd pregnancy I come to know that I had subclinical hypothyroidism bcz my tsh was 11.06 during 3rd weeks of pregnancy was not treated. So I changed my gynecologist and now she gave me loprin 75mg,levothyroxin 25mcg, mom c and Glucophage 250mg twice a day and she also gave coq10 to my husband for safe side my husband Cheked andrologist he gave qaz plus and clomid to my husband. I want to get suggestion are these medications are OK? Or should I change my gynecologist?
