Is Pregnancy Possible Through Non Penetrative Sex?

On the 04 of January which was one of my fertile days, my boyfriend and I had sex and he cummed on my butt and while I was wiping it off with a towel, I think I might have got some on my hand. After that while my hand was still a bit wet, I touched my vagina and it was also very wet. My hand was still wet with semen and I touched the inside of my vagina with it accidentally, could I end up pregnant???? Need answers asap): it is a day later and my stomach is cramping, along with a headache and my body is in pain.
