Very Much An Accident

I’ve been dating my boyfriend since we were sophomores and we’re now seniors in high school.
We make out a lot but have never gone all the way although he has gotten close several times.
A few weeks ago we were messing around in my room. He took my panties off and was rubbing his penis on my stomach when he came. It ran down between my legs so I ran to the bathroom and cleaned it up as quick as I could.
I didn’t think any more about it because I was sure none of it got close to my clit.
I must have been wrong because when my period was supposed to come it didn’t. I thought maybe I was just late but after a week I took a pregnancy test and I was pregnant
It was very much an accident since we didn’t have intercourse. We haven’t told anyone still trying to decide what we want to do.
