Spotting and weird discharge after having sex

I had sex for the first time. My friends don't even count it as sex. He did not go all the way in, as it was too painful, but I was bleeding afterwards. We didn't use protection, because he wasnt planning on going all the way in, and it only lasted about a minute. He did not cum inside of me, but I have a pregnancy scare. I spot a little, and my discharge was a weird brown color, but is now back to its regular clearish color. Am I pregnant? I am so scared, I have asked my closest friends and they assure me I am not, but I do not know what to believe.
