Missed pill

So I’ve been taking the pill for a while now but the last three months I’ve been really forgetful.

Month 1- I missed one pill in the packet but remembered to double up the next day.

Month 2- I missed one pill in the packet but remembered to double up the next day.

Month 3- I missed one pill in the packet but remembered to double up the next day.

I’m concerned because this happened three months in a row and I do have sex pretty regularly.

Should I be worried?
