still no period i’m worried

me and my boyfriend had a lot of sex this month, we always use a condom & and he always pulls out. He didn’t pull out one time this month but he had on a condom and it didn’t break or anything. i’m also on birth control but take zzzquil but heard it messes with the effectiveness of birth control so I quit taking it. I’m into my sugar pills and still no period!!! i’m stressing! we always use a condom so I should be fine ??
