Virginity, Period, Pregnancy. Pregnant?

I lost my virginity a week ago and i was supposed to get my period two days after, it was unprotected but he didn't go all the way in because it hurt so bad. I was spotting the day i was supposed to get it but never got my period. So i saw online that to get your period quicker is to have sex. So we had sex a few days ago and I went to the bathroom and i wiped and had some blood on the toilet paper. But that's the only place there was blood. So he fingered me and i was bleeding so i assumed i got my period. but now i am not bleeding at all and i just have brown discharge but i have all the symptoms of being on my period. I have very tender breasts, mood swings etc. Could this mean I am pregnant? Everything about my period is confusing me and it has never happened like this before.
