A childhood belief about getting pregnant

when i was like 7-8 years, me and two neighbour guys were playing and we had this secret spot where we used to play doctors and stuff. and ones while we were playing I had to take my pants off, and I don't remember how, but one of the guys held his penis close to my vagina, it wasn't inside me but it touched my vigina. Next day at school, the one in my class asked the teacher how to get a baby inside her stomach the teacher told the class, and said "the boy have to have his penis inside the girls vagina" and I remember what happned the other day. So I went around for 2 weeks or something worried I was pregnant lol. after I talked to my teacher and they told the girl have to have something called menstruation which I didn't have so, I was safe lol
