First of all, I'm very sorry for your loss all that you have been through. I also have two copies of MTHFR. Based upon my research, it is the second worst mutation of MTHFR to have However, as has been said, many doctors do not think it needs to be treated beyond baby aspirin and Folgard/Metanx. I however will be on longnecks for any other cycle that I complete. If this makes you feel any better, it is my understanding that most issues with this mutation arise in the second trimester. Many people do not think it has anything to do with implantation. What you need to check is to see if your homocysteine levels are normal. I think most doctors do not consider it serious unless your homocysteine levels are elevated. That being said, many women have been unable to carry to term without the use of lovenox or another blood thinner. Yahoo has a very good MTHFR group that you might want to check out. I think the issue with trying to sue here is that most of the literature says that being compound heterozygous for MTHFR does not impact implantation. So sorry that you had to go through this.
