First time TTC and after two days after Ovulation y started to have this itching and irritation. My Gyn says it may be that I’m sensitive to my Husband semen or I got an infection but I don’t lnow why. He send me a pill to take for two days but I don’t see any changes. I was thinking of getting some vaginal ovules but I’m not sure if I should. And the next appoiment is on tuesday. Anyone else had this problem?
