MTHFR then what?

Finley and I haven't been secretive about the miscarriages we've had after Norah, 4 in 2 years. We have gone through tests, prayed, gone to adoption Bible studies, and done foster care training. And here we are, trying to decide what to do next.
After all the tests, we know that I have a mild case of PCOS and 1 MTHFR C677t gene mutation. People with two copies of the gene mutation cannot break down folic acid, utilize B vitamins, and can get blood clots (in pregnancy, the blood clots can be in the placenta, killing the baby). I only have one copy, and lots of people do just great with one copy. But my miscarriage pattern (we've lost 2 babies after seeing the heartbeat) seems to be pointing to something immunoligical like this.
We are beyond the expertise of any doctors we know of in Arkansas. So, we have decided to become long-distance patients of the Alan E. Beer Clinic in California and finish our foster care paperwork. As a research facility, The Beer Clinic does some "cutting-edge" tests and treatments that aren't standared. We are going to get the remaining tests, see about the cost of treatment, and pray.
So I am currently peaceful. I am praying that we will be a part of what God is doing, whether through a miracle baby, foster care or adoption.
