What do u think?

This my my monthly cycle. I started my period on August 8th and was supposed to end August 12th but I started my pack on the Saturday instead of the Sunday because I wanted my bleeding to stop. Because I took my ‘Sunday pill’ on the Saturday, I had nothing to take Sunday and skipped the day. I never take my pill on the same time. Usually 8pm - 3-4 am it’s whenever I remember. My boyfriend came in me on my most fertile day when I was ovulating. Because I missed a pill, I’m worried I could be pregnant. Can I?
