You likely irritated things, but at 10 weeks, scar tissue is strong, and you don't have to worry. I had a lung infection before and after my surgery, and have asthma. I coughed nonstop, and was very worried I was going to blow out my wrap. Thankfully, it survived and works just fine.
Don't worry a bit. That said, be sure you have some good anti-nausea drugs...there's a bad Norovirus going around this year, and repeated vomiting can be very damaging.
