Sir , actually my friend had a unprotected sex and After sex her vagina remains wet and the vaginal walls feel swollen and she feels like there is a bump on the cervix. He also had an infection in his private part before sex but when she v wash used , the infection got cured.
She feel irritation all the time.so she just confused that is she's
pregnant or she got an infection.She don't tell about this to her parents bcoz as she is minor to please doctor suggest some point which is Important for this situation as per you.
