17??? PLEASE HELP AM I PREGNANT

So I'm 17 and two weeks ago me and my boyfriend were fooling around and we had unprotected sex , it wasent for long though because I told him I was worried about getting pregnant so he stopped he wasent close to cumming and didn't cum at all. But I know the whole big thing about pre cum . We had sex on one of my most fertile days. Fast forward to 2 weeks later a clear watery fluid came out of my vagina right after I got out of the shower I was master bating in the shower and once I came out it just poured out of my vagina but it wasent a lot it was a little bit . I've been googling about it and it says it can be pregnancy but most of the stories are about 28 weeks into pregnancy. Help me please I'm really scared
