I didn't get sick from my csection and I had been contracting for 3 hrs preop. (they say I wasn't in labor... not in labor my *ss... those contractions freaking hurt!)
I'm prone to migraine and didn't get sick from the epidural/spinal either!
nope didn't get sick from my c-section
Sometimes, just the intense contractions make some people sick! So it could just be contractions. Everyone is different.
oh, also if your c-section is planned you are told not to eat past midnight the night before. but since i didn't know i would be at the hospital the next day i didn't do that and i ate breakfast too... so that could have been a reason for me throwing up too.
i've had 4 c-sections and the only one i got sick during was the 1st one. i believe it was from the epidural. i threw up before the c-section (which was an emergency one).
