Unusual vaginal discharge?

So this might be tmi but I can't find anything about it online and too late to call a dr, my vaginal area was feeling kind of irritated a few hours ago, which seemed a bit odd but I didn't think anything of it, and now  getting ready to take a shower and I have this pink-orange kinda discharge which I have never seen before(I am 22) but it has no smell to it, could this still be an infection or what could it be?
