Need to visit lady doctor?

I think I need to make an appointment To go to the lady doctor. This past week my vagina has been itchy and I’m discharging red brown stuff (idk if it’s from my period or not) and it’s not enough to wear a tampon so I’m wearing a panty liner but it’s like rubbing my vagina raw because I’m sweating in my leg area and moving around at work. It’s so uncomfortable. I feel like I have a constant wedge in my crotch area but no wedge.. any suggestions on what to do?
