Is there a chance of me being pregnant?

Hi so I'm currently on the birth control pill and have been for about a year and 4 days ago I had sex with my boyfriend and we didn't use any other method of birth control and he did ejaculate inside me and today when I went to take my birth control pill I realized that the days did not match up meaning today the pill I took was for yesterday (Monday) when I was supposed to take a Tuesday pill today. This made me realize that I had missed a pill at some point and I tried to remember when I had forgot to take a pill and I realized I forgot to take a pill 2 days ago on Sunday which was 2 days after I had sex. I took Sunday's pill on Monday but I did not realize I had forgot to take a pill on Sunday until today. I took my birth control as I was supposed to on the day I had sex and the day after I had sex but as I said I forgot to take a pill 2 days after I had sex. I took yesterday's pill and today's pill together today but I'm just worried if its possible that I could be pregnant because of the one pill I missed. I also hear sperm can live inside a female body for up to 5 days so that's why I'm concerned. If anyone could let me know what they think that would be helpful thanks!
