Symptoms of pregnancy anybody know?

I have had period like cramps for two and a half weeks and my hurt. My LMP was may 19th and I got off may 24th. I've had headaches, backaches, low abdominal pain, more so in my lower left side. I have been bloated all month and hungry a lot more than usual cuz i never eat...I've also had a lot of discharge more than normal. Its not smelly or anything just normal just a lot of it my s are heavy they hurt. I should be starting my period n a week n 2 days.I did have unprotected the day I got off my period. May 27th and the 28th and last week.. anybody know what this could mean? My pt came up negative, but I took it too early I think.
