I have it, but I am heterozygous....as is about 30% of the population. The only reason I was tested for it was because my sister gave birth to a stillborn baby girl at 39 weeks. Despite extensive testing of my sister and the autopsy on her daughter, there was never any cause found for her death. When my niece was born, she looked perfect in every way. She died in the womb a few days before my sister noticed that she had stopped kicking. My sister had some follow-up testing done by her OB and it was found that she is homogygous for MTHFR. They thought this may have been what killed her daughter. It was recommended that for her next pregnancy she take extra folic acid and be given blood thinner shots everyday.
My sister subsequently switched to an RE since she is now considered high risk due to the stillbirth. The RE explained to her that even though she has MTHFR, it is not the kind that causes blood clotting. (I'm not sure if this is Factor V. It is just too complicated for me to comprehend.) Her RE told her NOT to get the blood thinner shots and that MTHFR did not cause the death of her daughter.
I was pregnant with my second child when my niece was born, and because I had the testing done and was diagnosed with MTHFR, my OB insisted that I take baby aspririn and extra folic acid. I also got a lot of extra ultrasounds and had non-stress tests every week during the last month because I was considered high risk due to the diagnosis. I took the extra folic acid but didn't take the aspirin. My son was born healthy with no complications.
Sorry this is such a long post! My point to you is....make sure a specialist sees your test results so he can determine whether or not your MTHFR mutation is the one that causes blood clots. If it is not, then you do not want blood thinner shots or aspirin that may cause more harm than good. Regular OB practices are not very well informed about MTHFR. FYI, my sister had a healthy baby boy before her daughter was born, and she recently had another healthy baby boy.
Since your miscarriages were early, they may have just been random genetic mutations that had nothing to do with anything. (So sorry that you had to go through the two miscarriages, by the way.) I have known SO many people who got pregnant after they stopped takling Clomid! I hope you are able to meet with a specialist that you like, and I hope you are able to get pregnant soon. Take care!
