It doesn't really matter whether he ejaculated in your or not, pre-ejaculation can and does cause pregnancy so you need to be using condoms at all times. Many things can cause the sensations you're feeling, not just pregnancy. All you can do is wait until your period is due, and if it's late then take a pregnancy test with first morning urine. If you're trying for a baby you should be using protection EVERY time.
you need to take a test 2 weeks after u had sex, see if u miss your period, also pull out method or peeing after does not make u not become pregnant, if your not ready for a baby then get on BC and use condoms. im not trying to be hateful im just trying to help you.
