Am i pregnant??? tmr will be day 34 without a period?

I had sex on the 6th of June. He used a condom but for a minute he went in without one. I did a pregnancy test and it came neg. My period is due it's day 33 all week i've had period pain like symtoms. It seems like it's about to come, but it hasn't. I put a tampon and it had some like a little bit on the tip it was pink/brown not red. I've been having period like symtoms all week my tummy is growling, diarreah, shaky legs, and i'm so tired. I also get this real dry throat it feels like it need pop or some sort of fizz to get rid of the feeling. I can't explain it like severe dry i've never felt that way before. My tests are negative. My boobs are super sore... No period but it's been 3 weeks since i had sex..should i be okay???
