Birth control screw up

Somehow my prescription for 1.5mg burn control didn’t refill, and tomorrow is Memorial Day, which means I won’t be taking my BCP Sunday or Monday night. I’m sexually active and do not want to stop taking the pills (obviously).

I still have a pack of my old ones that are 1.0mg. If I took a full pill and cut one in half, would that work? Would I technically be taking 1.5mg? Or is that not a good idea? Would it be better to take one of the lower dosage, or just none at all?

Any advice would be helpful thank you :)
