hii, im 16 years old and had unprotected sex on november 26, 4 days after i used plan b. A couple days after taking the Plan B pill my vagina was very itchy and i had discharge and it didn't hurt when i peed it actually felt good. i waited 3 or 4 days to see if it would go away and it didn't so i went to the gynecologist and she diagnosed me with a yeast infection. She gave me monist at and its now 4 days after and i still am very itchy and uncomfortable... Its almost been 2 weeks now..
