Is my birth control ineffective now?

Hazel

I just came back from my boyfriends house this morning and I had to head straight to work. Today was 38 degrees outside, so fairly cold, and I had to leave my pills in the car in my duffle bag.

I was at work for a good 8 hours. My car wasn’t particularly freezing or anything when I got in it, but it wasn’t the ideal temp for having your pills in.

Would my pills be less effective now that I had them in a slightly cold car all day?
