First: Thank you ladies for your congratulations/advice.
Second: To the person who asked, yes, my XH told me he was filing for divorce when we were told I'd need fertility treatments to conceive. Sad and crappy, but actually not as uncommon as one might like to think.
Third: I did speak to my sister yesterday, and the conversation didn't quite go as well as anticipated. Perhaps I caught her on a bad day, but the reaction was "How did THAT happen? I thought you were infertile" and "Just because you're having a baby, doesn't mean you have to get married" and "Well, at least you have time to lose the weight so we don't have to get your dress altered."

So yeah. Fun. But I didn't want you ladies to think I was ignoring you or didn't appreciate the advice. Also, I think I may stick around, this is helpful/entertaining.
