Sounds like you are doing the right thing for you. I can't imagine what it felt like (and still feels like) to have lost a baby at 37 weeks. That's just wrong!!!
You do have a VERY low FSH though. Yours is a whole lot better than mine, so I may be in for some heartache ahead as well.
So you have a child already that is yours? Me too. I think that's why I am okay with the idea of donor eggs if we fail (DH not cool with that... yet).
I feel very blessed to have my daughters (21 and 18). I feel greedy even trying at my age - but my new DH has not had children. I vowed to give it everything I had until age 46, and so I am.
My second EC won't be until early April. I really want to transfer then, but my dh may want to "bank" anything we get from that as well and go for a third. As I've said before, he is trying to maximize our chances of more than one child (seems like we are waaaaay into God's business, but I'm trying to let dh call the shots since he isn't in my position - already had children).
God bless you, Joy, as you go into this next attempt. You are correct about the younger eggs - my docs all say the same thing - it's practically a sure thing with those younger eggs!!! Better start thinking of names!
