Brownish discharge: pregnancy symptom or period

I've had unprotected sex with my boyfriend. My period is due on the 28th, but on the 25th I had brown discharge, but it wasn't a lot. t I'm nervous on weather its a early pregnancy symptom or just my period coming. So I curious to know does this mean I'm pregnant.

The only thing you can do is take a test. You can get a thing called implantation bleeding which is a light bleed when the egg settles in the uterus. Go buy a test before you have a freak out. Mel x
