Yep, what julija said.
I almost never post about my pregnancy on facebook. I spent a week in the hospital in May and never even mentioned it on my facebook page. It's just not necessary. I don't care for the extra attention, the people who needed to know, knew where I was and why and what was going on. I'm having some issues (hopefully minor) this pregnancy, only the people who need to know, know about it, that does not need to be my entire FB friend list. I'm private about things now, partly to protect myself from dumb but well meaning comments, partly because I have friends who have struggled to even get pregnant, and partly it's just easier this way.
As for discussions about delivery,etc., since I had a classical c-section the first time, no one in their right mind would argue we should try to make it to 40 weeks. Our first daughter died and I would have absolutely no qualms about saying "I'd much rather have a living baby at 37 weeks than a stillborn baby at 40 weeks." I would imagine that would shut them up pretty quickly.
