My boyfriend got another girl pregnant what do i do?

It really depends on how you feel about him. I personally would break up with him after finding out something like that because that'd make me guess he's the irresponsible type to bail. If he's a good guy though and is taking care of the girl he got pregnant then it shows he's at least the type to handle his problems and not run away from them. If he got her pregnant WHILE you were dating then dump him! You can do so much better I'm sure then being with a cheater! It really depends on your situation. I'm a teenager too and I know if my boyfriend EVER cheated on me I'd leave him in a heartbeat. To me, cheating is unacceptable and people should be completely honest in a relationship if there is to be trust. If there's no trust then there's no true relationship. If you want to ask anything else or want to go into details on the situation feel free to message me I'm willing to listen. :) Good luck sweetie.
