You should talk to your dr treating you for disautonomia if you are concerned. However, I recall past posts saying that some women felt better than ever while pregnant, symptoms improved, etc. When I asked Bev in Toledo recently, she said that POTS (at least for me) was not a reason to not have kids. (I'm not trying or anything, just wanted to know for future reference.) I think I once read that some women feel better during pregnancy because of increased blood volume. So, if you are worried, talk to your dr, and if you have concerns, definitely ask your ob., but try not to worry too much. Not everyone has the same symptoms/experiences the same things. (This is a lot more than I thought I'd type, as I've never been pregnant!) Good luck to you! Meg
