as PP said, there is an AMAZING over 40's board, though you are welcome here as well.
As far as Dr. Check he has a BUNCH of folks on this board who are either working with him, are pg after working with him or have kids because of his care.
I, personally, am 7 month pg after almost 4 years, an FSH up to 58 at one point, two TOP dr.s kicked me out... and Dr. Check was able to fix my hormones and get me PG in 7 cycles. So, I'm a believer!
But: I see a lot of wonderful things about Dr. Davis, too! A number of people found success with him as well.
I always think seeing someone else is a great idea, so chat with both of them!
Good luck to you and welcome,
PS- Dr. Check's office is a bit different than what you might be used to... looks at the main page here and find the "search" button. Do a search about first visits with him and read up a bit. He is eccentric but worth it and, if you know going in, you'll be ready for it! He's not your typical RE... but typical kicked me out and with him I found success!
