Pregnancy and dry humping?

dream

What are the chances of getting pregnant whilst drying humping. I not sure if he came or not but we were both wearing clothes, underwear and I was also wearing a pad because I was on my period. What are the chances that I’m pregnant?

Edit: thank you to everyone that has already commented but I didn’t mean this to be a stupid question. I wasn’t educated well and I am still 16. Please don’t judge me, all I wanted was some advice.
