Post-period discharge

I’ve noticed that after my period ends I get smelly discharge.. I tried to get an appointment last month but due to covid I guess it wasn’t urgent for them to see me in person I got video call from a doctor but he was zero help he prescribed me some pills but I never got them because he didn’t see me in person and i wasn’t sure if it was gonna be helpful because he was just assuming things. After a week I was back to normal but it’s happening again and it’s very uncomfortable.
