Is it possible to become pregnant from a guy rubbing

Patient: Is it possible to become pregnant from a guy rubbing against you without entering? I feel like I am stressing too much over this, but about two weeks ago my boyfriend rubbed against me naked like that on my… There, and he did not enter inside of me and it only lasted like 2 seconds. I feel like I couldsbe pregnant because I’m 4 days late for my period, but I’m usually late. could I be? How likely is it? And if I am then what are some ways to self abort at home?
