Hi Kelly!
Congratulations on the BFP! I'm so happy for you!
I did not cough any more frequently while pg. When I did cough, I tried to squat or sit because if I was standing (or swimming, oddly enough) my round ligaments would pull and hurt like nothing I'd ever felt before. One time I swear I almost passed out. The other times weren't nearly that bad. But that is NORMAL! All the pulling, stretching, cramping, all of that is normal pg stuff. You are creating a life in there. It's hard work and you're going to notice lots of changes in the coming weeks even though you're not showing yet.
I did not do IV antibiotics while pregnant. It did inhale Aztreonam and I took Zithro. That's all I can remember. Oh, and inhaled TOBI as well.
Cough all you need to girl. No amount of coughing is going to hurt that little bean of yours. s/he is very well insulated!
