I was at a party 5 days ago and I had sex with this guy but it was for a couple of minutes and I just finished my period I don't know if he came inside me or not? And I was feeling sick that morning but I never was sick at all even the next couple of days and I had a really runny nose, but my boobs feel fine, I don't feel sick, or I haven't got any other symptoms at all? But I'm still a bit unsure?

Feeling sick could be from the party, a runny nose has nothing to do with pregnant.

Now could you be pregnant, of course, and beyond that, you could have a dozen various STD's.

You will not know about the pregnancy till your next period is due.

You should call the guy and ask him. You should also go to the doctors and get checked out since you had unprotected sex.
