Burning / itching ONLY the days after period

So this is something that I’ve noticed for the past 6 months, I think. The following 1-2 days after my period has completely stopped I get very itchy down there, sometimes even a burning sensation. Then it’s gone for good and I feel great. Sometimes during my period I feel like I’m developing a rash where my vagina rests on my panty liner and sometimes the irritation is only on the outside of my vagina, sometimes it’s just barely inside. Today (day after period) I am experiencing burning while peeing. This is new but it’s gone mostly away since I’ve showered and gotten out of my work attire.

I’m curious if panty liners/tampons can irritate me down there to this point? Is it possible to be so sensitive down there that the slightest change in the liner brand can irritate me so much? I don’t remember it happening when I wore the big ol’ pads. I am barely sexually active, and when I am it’s the same person so I don’t believe it’s anything related to a STD/STI. I clean regularly and no longer use any products (Summers <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>) to clean down there.

Yes I know a doctors visit would answer more than anybody here could but my schedule is very busy at the moment and it’s happening right now as my period just ended, so by the time I was able to go the issue will have cleared up. I am planning on a doctors visit once I return from my vacation this coming week, but some suggestions and solutions from my gal pals would be appreciated! Thanks!
