Today is the 13th day till my next period according to my period tracker app, and i let my boyfriend insert his penis with no condom, we didn't have sex but it was just in and out a few times, not even the whole way if that makes any difference, and we were doing things before (oral) so it's been a while, and when I got home i had a lot of really sticky slimy clear stuff come out of me like discharge, he didn't ejaculate in me but I worry because of pre ejaculate, would it be likely I miss my next period?
