I found out 2 years ago that I have 2 mutations of MTHFR. After 2 MC I thought we had found the answer. Then I did a consult with DR Kumar and he pointed out to me that I had 2 perfectly normal pregnancies 30 yrs ago with no complications and didn't even know I had MTHFR back then so it couldn't have been a factor, that I was born with this and have had it my whole life. I did struggle the cycle before last with a thin lining after years of great ones (11mm plus) so we tried the estrogen patches this time and got a great lining with alot less mood swings than the pills. I also took prednisone for 30 days beginning 5 days before the transfer. That was the only thing I did differently other than being under Coopers close supervision for the whole time I have been pregnant (currently 9 weeks)I have BW every week and they adjust my patches and PIO accordingly.I will be under thier care until I am 14 weeks and truly think the continueing meds have made a huge difference. This is the first time I have ever gotten pregnant with 3 day embryos and was so unsure of then we put 3 in at transfer.
