MTHFR Gene mutation question

Saundra
So I found out from the docs yesterday I have a whole lotta stuff wrong with me and that's why I keep having miscarriages. One of the problems is I have the MTHFR gene mutation, but I guess just one, if that makes sense? I've read other people having it and they're on lovenex. My doc is just making me take extra folic acid. Is that normal?
