Multivitamins to prevent miscarriage?

Hi everyone

I had my second early loss last week in the past two months.

I was reading that some vitamins prevent certain things but not sure how true that is.

For example I read that selenium helps in strong does (my current multivitamins only have a small amount) and vitamin e can help with blood clotting antibodies.

Also higher doses of folic acid?

Probably all nonsense but I just wanted to see if anyone has tried anything different and been successful or spoke to a doctor. I have requested an appointment to ask him anyway but not till next week. I also know some people will say they aren't caused by anything and I understand that but the why I'm feeling at the moment is that it is me :(

thank you xx
