i’m 15 help please

siena

my boyfriend and i spent all day together and he didn’t cum or ejaculate at all, and him and i were together and he rubbed his penis on my vagina but not inside, just on. i don’t keep track of my period normally so i just get it when i get it but now i’m scared. i got an app and i’m supposed to get it tomorrow. all day today i had a cramp and felt a little bloated... my boobs don’t hurt but my nipples are a little bit sensitive. is there any way i could be pregnant? please help i can’t ask a doctor or my parents.
