OP here. First, thanks PP for sticking up for me. I am so thankful for the kind, as well as honest, responses.
There are so many nice ways to tell me what I'm considering is kind of crazy. I really appreciate the different perspectives. I turn 41 in December so by then I'll either be pregnant or done with childbearing. I certainly don't want to drag this out. My doctor thinks I'll be fine considering my last three pregnancies/deliveries (as much as she can predict of course), and my kids are in sports but we're pretty low key about that. We know we're not raising any Olympians here...just kids who like to run around and have fun. We are not near family but are considering a move to be near all four grandparents and that will help.
If you have more stories or advice to share, I'd love to read it. All in all, I feel like life will be great either way. I guess I'm mostly holding out hope for a little girl or confirmation that my husband and I only produce boys!

I know if it is a boy, I will be slightly disappointed but that will be replaced with happiness that I got one more miracle in my family.
