Average time it took to conceive?

My boyfriend and I have frequent intercourse and he always ejaculates inside. We have both said if it happens it happens. We have only been doing this for 2 months now and I am supposed to get AF Friday. It's silly, but I hope I don't get it but I feel I will. I have this stupid fear I won't ever get pregnant. My periods have been regular for a long while, but it's still a fear. Anyone else have this stress too?
