Hi,I had unprotected sex and i took emergency contraceptive. All seemed fine and then after 3 days, I started getting itching around vagina and inner labia. I scratched it and the itching got worst and it all got red and i saw some rashes on inner labia too. I was really worried as i can't share this with anyone. I read a lot about the yeast infection and also that it can happen because of contraceptives. I tried applying yogurt and it did relive the itching a lot but I still see rash or something that i can't explain what it is. The discharge is odorless and since i have started applying yogurt, i don't know the thin white watery discharge is yogurt residue or some discharge. I am too scared to go to a doctor and I want to know what i have is a yeast infection or STD. I really need help. Please help me how to cure this. Please
