Great news on the E2. I bet you get at least 8 mature ones and who knows, maybe you'll even be pleasantly surprised with a few more they didn't catch on the ultrasound. 7-8 is still a pretty good response.
IMO, that dismal 1% figure doesn't apply to you because that figure is going to include women who have never been able to get pregnant, who are unexplained or who have other issues that are much more difficult to treat. Also, it's really hard to apply statistics to 40+ year old women because there are so few of us actively trying at this age. That really skews the statistics.
So you are in a class all by yourself which is terrifying and encouraging all at the same time.
Is ER in the morning??
