Hi all. I, too, am closing in on 37 and DD is 2. AF returned way too early as far as I'm concerned (about 9 months) but I was under tremendous stress within our household. I think that had something (everything) to do with it, especially because DD was very attached to nursing (still is).
Somewhere down the road I would like to conceive again; I'll see where I am if/when that time is right.
Good luck to you all!
