should i see my doc??

my next period is in 11 days and like over a week ago, me and my boo did doggy, straight after my period too (i wasn’t sure if i was 100% off yet tho) but ever since then, there’s been like a browny/yellow mucus sorta discharge shit coming out my vagina, i thought that it was just left over period before so i left it but now its clear discharge, should i just leave it? like is that normal now? there’s only small bits of brown now.. like so much less than what it was so i’m pretty sure ive cured myself but if it gets worse, should i see my doctor? even tho there isn’t much they can do?
