HELP PLEASE!!!😭😰

Giovanna

Hello I've been spotting 5 days before my period the blood has been light pink to brown and I'm supposed to start my period tomorrow. I have had unprotected sex but he never came and it was only in the beginning then he put on the condom and we finished that way. I just took a pregnancy test and it said it was negative. I'm worried am I pregnant or could it be something if so... what are the other possibilities?

* I HAVE NEVER EVER SPOTTED BEFORE MY PERIOD!
