I am new to this thread and I am scared to death!!! On Saturday morning we had our first IVF transfer using a donor egg. Our donor was only 25 , I am 41 and we determined that my eggs are poor quality so we moved to this option. Anyway.... my question is this, I don't understand the embryo grading and ours was only graded a "C". I told my dr that our kids get in trouble for C's, so I am not encouraged. We transferred 2 5 day embryos and she said there is a 55-60% chance of pregnancy and a 20% chance of twins, BUT... considering I have had a negative test monthly for the last 3 years, I am scared to death! Are there any encouraging words anyone can offer? Success stories? Etc?
