Cluster of symptoms! Pregnancy possible?

I lost my virginty to my boyfriend at the beginning of march and I was bleeding. A week later we tried to have sex again. I started to bleed heavier than I did the first time and I didn't have my period. A week later I did get my period and when it went away we tried to have sex again. He couldn't "get it up" so he decided to finger me. I didn't feel anything so I made believe that I did. Then when he finally "got it up" he entered me. At first I didn't bleed and I couldn't really feel anything. Then as he pushed and pushed it in me I started to bleed and I still didn't feel anything. He was really upset that I keep bleeding. Now I'm tired. I get emotionally for no reason, my appetite is changing a little. We only used a condom once. My mother thinks I'm pregnant I took a test and it said that I wasn't. What is wrong with me?
