I recently had unprotected sex with my partner but he did not ejaculate on me. is it possible for me to get pregnant ? im devastated.

Ejaculation: Any time there is a penis in your vagina without a condom or some reliable form of contraception ( the pull out method is an unreliable method) there is a possibility of pregnancy.

Only takes one: There is often some semen in pre-ejaculate, so the pull-out method is not very reliable. However, if this was your only encounter, it is not likely to know if pregnant after only a few days. If period late, check home pregnancy test.
