I just have a very silly question- im panicking a bit. so first time in my life i had sex whilst not on a pill. and my boyfriend never finished in me, he had condom on. but then i was reading a lot about precum and how you get pregnant from it also.

Condom is effective: Properly using a condom is effective contraception, regardless of what else is happening. Using a condom, but not "properly," makes it less effective but that would vary from situation to situation. Fertile couples having sex always have a chance of a cute, surprise baby. That's the way life is. So, one just has to decide, "Did we use condoms properly?" If yes, then we don't worry.
