Discharge

So I've been getting this weird discharge I was thinking it was an std so I went to go get checked out and everything came back clear. So I just don't get why I've got this discharge then. They also checked for bacterial vaginosis and that was clear too so I'm really curious if anyone else has this problem and wether it's just somthing that women get or if it's just linked to diet or somthing?? 
So basiclly does anyone else get thick whiffy discharge?? 👀😂
