If he never entered your vagina and there was no sperm that entered your vagina, then no - pregnancy is impossible. If he ejactulated ON your vagina, there may be an incredibly small chance. But it would have to be when you were ovulating and those sperm would need to be really really smart - and we all know, sperm are not smart.

You aren't pregnant. However, if you get on birth control, this is something you won't need to worry about! Good luck.

your not pregnant

and please dnt typ lyke dis itz uhnoying

It could happen because it was near and sperm can travel. But it is very unlikely. I would stronly suggest if your going to have sex then you better be on birth control so you don't freak out about such things. I doubt you pregnant so please be careful next time.
