Sex/pregnancy

I got my period in February. I had sex without protection. I took two pregnancy tests in March (both negative) I miss my period in March, April and may. I took two more pregnancy test in April (both negative). My boobs hurt and feel weird and my stomach feels bloated. Maybe I’m just paranoid about my stomach. I’m not sure if I’m pregnant or not. Someone answer.! I need advices. I called my gyno but they haven’t called me back.. it’s been a week also. I stopped taking my birth control (3month supply) in February so I’m not sure if I should start taking it. :(( everyone says I’m not pregnant but my aunt is worried and thinks I should be worried too!
