Help me

So my period is 3 days late. I’m getting super watery discharge and I threw up earlier because I coughed and it made me sick I guess? And also really bad cramps like baaaaadd. And I’m super emotional. And bloated a little bit but if I suck in my stomach I get a sharp pinch right under my belly button but just a little bit lower. Idk last time I had unprotected sex was July 4th and 8th? And before that May 5th but I got my period after that. Confused please let me know.
