Am I pregnant!?

I had unprotected sex, he pulled out but I still have a feeling that I’m pregnant. This was on February 5. Today is the 14. I’ve been having strange cravings, staying hungry, and i have been nauseated. 7 days ago I had an extremely bad tight balloon feeling pain in my left ovary. It caused me to have a mixed discharge (bloody and watery). My stomach has felt “full” since. I’m constantly staying nauseated and hungry. I bled a little today and then it stoped. I’ve been bleeding on and off (brownish discharge) I’m not suppose to have my period for another two weeks. I took a pregnancy test but it read negative. I was told that it could be to early to tell. Could I be pregnant?
