Am I protected?

I started taking the pill in October of 2019, and I am still regularly taking it. I missed a day in March, the pills hadn’t arrived at my pharmacy so I had to skip that day.

I have heard that they need to be taken at the same time everyday to be effective, I take them within the same few hours (10 pm- 12 am) every night.

In order for the pill to be as effective as possible should I start taking the pill at a certain time? Or should I reduce the time frame to within an hour period?
