it's the frist time I post here, my story is I had a premi boy at 27weeks on Sep 2007, now I am pregannt again, as I had a premi baby history so the doctor did test my blood's DNA group, the result shows I have MTHFR problem in my blood.

I just wondering is anyone has the similar situation as me? I am quite concerned about this as I never have any blood problem in my life and this one according doctor said it can cause high risk to miscarrage.
