Hi, I had two miscarriages 😔😔

I had two miscarriages and both of them with twins, first identical twins and second pregnancy wich I missed one month ago was fraternal twins, the doctors dosent give me a reason why they say everything is fine here where I live. So I went from here to my birth State and there I did all analysis and they told me that I have an high thyroid gland and high Prolactin and for that I am miscarring, does any of you experienced this If yes what did you use and does that help? I am using Dostinex tablets for Prolactin and for thyroid gland still nothing. Thank you 😊
