I had one boy, he is 10 years old and I was trying to have another one since 2010 but I got 4 miscarriages. My problem is I can get pregnant easy but when I get pregnant hypothyroid will come and I'm taking Madison for that . Every time My pregnancy will continue until 6 or 7 or 8 weeks after that no hart beet and pregnancy is small. Can anyone have some solution for me ?
