Don’t remember taking my pill

So yesterday I remember my pill alarm going off and going to get the pill from my pack. I was on the phone during this and I can’t remember if I actually took the pill or not. It’s not in the pill pack anymore and I looked all around my room and on the floor and I don’t see the pill anywhere. I probably took it but what would happen if I didn’t? Today I took my next pill a few hours earlier (4 hours) just in case. I had sex last night and he pulled out but it’s just scary that I don’t remember taking the pill.

Also this was the second week of active pills
