Could I get pregnant?

I know this sounds dumb af, but around two weeks ago this guy I'm seeing kinda just rubbed his dick down there (through leggings and pants) I don't know if I'm being paranoid and I feel stupid for asking, but is there a possibility?
I'm really young and I don't want to get pregnant.
Also, my period is late, so I think it's not helping my paranoia, it's just nibbling away in the back of my mind. 
Really would love feedback if you just think I'm being paranoid, or if you think I need to take a pregnancy test😅
Thanks💖
