If you didn't use a condom but the boy said he will pull out if he nut can you still get pregnant?

Yes That is called the withdrawal method and it is notoriously unreliable, If you are not pregnant now don't let him do it again because you will definitely end up pregnant eventually. Men can tell when they are about to have an all out ejaculation when they orgasm, but they cant tell when some sneaks out before hand , And it happens.
