Miscarriage rates over 35

[waiting4ever]

I am 37 and have just had my second m/c in a year with IVF.  These were both FET cycles, and ended between 8 and 10 weeks.  Does that make a difference?  We have been using donor eggs as well.  Donor was 30 when eggs were retreived.
We still have 3 embryos left and have decided to give it one last try.  What are our chances for success?  Is there something we can do to help prevent another m/c?  Since I have Endometriosis, I have been thinking that this may have been a factor as well.

My second husband and I would like to have a child.  But, I had my tubes tied after my son was born 8 1/2 years ago.  The only doctor in town that does IVF says he will not do it if a woman is over 40.  I'm almost 42, but young looking and young at heart.  I don't smoke, don't have high blood pressure, etc.  I was wondering if there is anyone who might have had IVF after 40 and what they experienced.  Or, if anyone has any advice, please help.  Thank you.

My first question would be why donor eggs at 37, I can only assume premature ovarian failure. And I assume the fresh donor egg cycle was negative and then came the 2 FET pregnancies with the donor eggs that miscarried. First the success in 2 FET pregnacies, maybe not the outcome, but this is a positive. FET pregnancies are against the odds in the 30 to 40 % range of achieving a pregnancy at all and it happened twice.
Second the number one reason for miscarriage is genetics, with a 30 year old donor the miscariage rate is equal to the general population 30%. It is the age of the egg NOT the uterus for the high genetic component to miscarriages.

Two pregnancy loss with 30 year old eggs between 8 and 10 weeks,  I would start looking at a diagnosis of recurrent habitual abortions. There are a variety of reason for RHA, recurrent miscarriages and it maybe that some of these should be looked at. But keeping in mind that FET does have a lower take home baby rate than fresh cycles.
Hope it helps,
