Am I pregnant?

[Anonme924]

Hi, I'm a 16 year old female. My boyfriend and I have not had sex, but yesterday we "dry grinded" without clothes (genitals touching). He ejaculated in my mouth and afterwards fingered me (there was not any ejaculate on our fingers as far as we are aware). We then "spooned" (more genital touching) but that was a few minutes later-- I think I was thorough in collecting the ejaculate and sperm dies outside of the body, correct? My last period was February 4th and I am supposed to have my next one within the next 3 days, so I am having cramps that (I hope) are menstrual cramps. Is there any possibility of being pregnant? I've done as much research as I can and I think the chances are low, but I would like some reassurance. Thank you.
