I am 22 years old, we have been trying for about a year and a half. I am about 5 weeks, I have had 3 m/c, and been through a bunch of tests, the docs think they have it figured out...i have a low thyriod, and my body lacks folic acid, and b vitamin(which causes my blood to clot really easy) we just found out and i am really excited....this could be it!
