Could I Be Pregnant?

Had sex yesterday and today. And I think i started having egg white CM yesterday. Today, my boyf pulled-out and came. After that we took a brk for about 30mins - an hr? Then we did it again but i sucked his dick for a bit before he put it in again. Knowing that his precum might still contain sperms from the previous ejaculation and my fertile window has just started, will I be pregnant?
