Lovenox and mthfr *someone please answer

Ugh i am so confused .

I have mthfr-homozygous .

I have had 7 miscarriages by two different partners .

I am preggo again first time in Almost 3 years . Furthest I have ever gotten 10.5 —-

With my last pregnancy i got the furthest i was on lovenox and progesterone .

This time i have been on the same , although my doctor is now saying that they have found that lovenox isn’t a key factor to preventing miscarriages now & told me i could get off it now .

From everything I’ve read online a lot of people have had success with it . I’m just confused , bc i feel like it’s helped me so far . Or maybe it’s just a coincidence.

I am at one of the top high risk facilities in Texas . They know more than me , since they research for a living . But my gut is telling me to keep taking them ... bleh
