nuva ring was in the fridge but my fridge wasn't working

So my nuva rings have to be kept in the fridge, but the fridge wasn't working. They were probabaly in there for about 5 hours b4 I realized it wasn't working. (just moved into a new house n that's why we didn't notice any sooner) The box says they have to be kept in the fridge. Are they still good to use or would u get rid of them? 🤷‍♀️
