Question???

Me and my hubby are trying for a baby I got a positive on my ovulation test Friday night and then we did it early Saturday morning well he finished and instead of me getting up and use the bathroom I fell asleep with his sperm inside me and plus I didn’t go pee, well anyways right now I feel itchy but I don’t have a odor or discharge just feel like raw down there. What could it be from ? I never felt this way before at all
