Help meee

Hi! I take sprintec and recently I Had unprotected sex where he finished inside me. My pills had been out in the Arizona heat with me for a few hours a few days in a row and it is consistently 95-100 degrees outside. I was wondering if every time I have a sexual encounter while on the pill without any other form of protection if I should be worried as it has a 9% failure rate. Also would the heat counter my pill and make it unusable? Thank you.
