40 and TTC for the first time

Carol
Hi. I'm new and trying to get a handle on all the acronyms. 
I'm trying to conceive for the first time in my life. I've been pregnant twice before, but it wasn't from trying.
I have no children.
So, we've been trying for about a month. I read the stats, and got myself all worked up!
Anyway, I'm here now to get some tips and encouragement.
