I have sex with my boyfriend he pulls out before he ejaculates inside me is there a possibility that i can get pregnant even if he doesnt come in me?

Yes: Any time and erect penis is inside the vagina of a normal women there is a possibility of pregnancy. The problem is that sperm are coming out of the penis in the pre-ejaculation fluid even prior to ejaculation. This is a common way for young women to get pregnant. If you don't want to become pregnant, you should get on a reliable birth control. There are many sources where they are free.
