Could I be pregnant from fooling around...

Elizabeth

Ok I know this is stupid but my boyfriend and I have been fooling around naked and he’s put his penis on my vaginal opening but never penetrated it. He’s also never come anywhere near my pelvic region or basically anywhere but my mouth. My period is 18 days late and has been pretty irregular for the past year but never this late and i’ve never fully missed a period. I have no symptoms except for being moody and irritable. I know that you basically can’t get pregnant without penetrative sex, but from what I’ve said is there any way that I’m pregnant? Also I took two tests on day 15 of being late and day 17. They were both negative but I took them in the afternoon is it wasn’t my first morning pee. Help!
