does anyone know what this means!

hi! me and bf had sex but it was very quick like few seconds at most bc he finished way quicker than thought (was our first time doing it as a couple). i’m having brown discharge now, is that concerning. we have done other stuff and idk if it means sign of pregnancy from a time i thought i got cum down there bc it was on mg hands and then i wiped to use bathroom and totally forgot. my period is like 5-6 days away so i don’t think it’s bc my period idk what coukd it mean? we did use a condom as well. thank you!
