Dryness after period?

18mos pp (am I allowed to still post on here @ 18mos pp?😅😂) and after my last period, I’ve been experiencing vaginal dryness as well as some itchiness. I barely have any discharge, almost nonexistent honestly. What could it be? I made an appointment with my OB but it’s not until the 21st and I need answers NEOW 😭
