i need some help

i’m supposed to start my period today according to my app, today would be my 30th cycle day. i didn’t get the regular ovulation discharge this month, and i always get stressed i could be pregnant. i haven’t started bleeding yet and my discharge is clear when i wipe. my boyfriend and i have never had sex and whenever he cums i always have pants on. we were dry humping him in just underwear and my shorts and underwear still on, but he didn’t cum near my vagina, is there any chance of pregnancy? and if not can you explain what’s going on?
