Recently I moved to a new place for the summer. It was a 5 hour drive and in the middle of it I wanted to take a break so I got out of the car to go inside a food joint, and I was probably in there for about 30 minutes.

The temperature outside was around 80°F at the time. My car got pretty hot, but it cools down pretty fast.

I was wondering how much this might effect my birth control's effectiveness or if this would cause it to become ineffective?

My birth control is Tri-Lo-Marzia.
