left my birth control pills in hot car???

i left my birth control pills in my purse in the car for 3 hours on September 1st (day 12 of cycle). i know it was in the 90’s because i was at the beach. were my pills not effective anymore???? i had sex twice after that (day 17 and 21 of cycle) with a condom and he pulled out before he came so he did not cum inside me. i never missed a pill during that pack and i got my period at my regular time, September 18th , so i should be okay right??? im not pregnant??
