Yes, anytime you have unprotected intercourse, there is the risk of pregnancy. Prior to ejaculation the penis leaks pre-ejaculatory fluid (pre cum). This fluid can contain sperm, which could result in a pregnancy. Therefore, it is possible to become pregnant, even if ejaculation has not occurred in the vagina.
If he ejaculated outside of your vagina, then put his penis in, there may still be some semen remaining in the urethral tract. This also could contain sperm and cause pregnancy.
