(old eggs)

.....that was the verdict. No big deal, the OB said, you just have 40-year old eggs, which are not as healthy or vibrant or (was she going to say fresh??) .... as they were when you were 35. So, this is what often happens - 1 out of 75 times to 1 out of 50 times for a gal your age.
So, based on her observation, I am in great company - as most of my g/fs are over 40....I just stand out though, I guess, attempting to hatch one of those old eggs :)
