TMI Infection?

So I was wondering what a pregnancy yeast infection feels like. The area around the outside area of my vagina is itchy and sore. The groin area when the hip meets the torso where your underwear sit also itches and sore. It’s been like this for about over a week. Hydrocortisone cream isn’t helping. It’s been very hot and humid in my area. I do wear cotton shorts and underwear. When I’m home I go commando. Time to call OB in the morning?
