MTFHR Minor - conceiving post miscarriage

S

Can anyone else with this gene mutation give me any insight? Have any of you who have miscarried, found out you had it afterwards, successfully gotten pregnant with intervention? My sister had 2 miscarriages, and the doc tested her for this and found out she has the minor version of MTFHR. Now that I have miscarried also my doc wanted me to test for the same thing and sure enough I have the same thing. The minor one specifically also. I don't think that's a coincidence. She has since had 2 beautiful healthy babies. Has anyone else had the same thing? They put me on folgard rx , which is basically an extra 4 mg of folic acid in addition to the 1 mg found in prenatal Vitamins. I'm Finally in my ovulation period post Miscarriage so hopefully I can conceive this cycle. 🙏🏼🙏🏼🙏🏼
