Hey y’all please help me figure this out

Why do I get this color discharge before and after my period? It’s confusing. I’ve had chlamydia before but then I had straight up yellow discharge 24/7. So having a sorta yellow to really yellow discharge right before and right after my period is odd. I don’t have tons of discharge throughout the rest of my cycle and when I do it’s just clear or white. I’m confused any answers or suggestion would be appreciated! Xoxo

Thanks in advance!
