So I had sex for the first time about two months ago but I got what I thought was my period, it was heavy and brown and it lasted for about the same time as my period. I wore a tampon the whole time. But I am still worried. Could I be pregnant?

I "bleed" Brown Too Sometimes, When I Asked My Doctor She Said It Is Just Dried Up Old Blood That Was Still In My Uterus Or Whatnot. I Don't Know How True It Is But That's What She Told Me.
