i am 20 years old, female, 5'2, 90kg. this past few days I have noticed yellowish brown spots in my underware. sometimes it(private part) is very itchy. 2 weeks ago I have taken antibiotics amoxicillin 500mg for tooth problems. It was for 7 days and after extraction of teeth I took another 5 days. I am very concern because I also experienced a very foul smelling urine last 3 weeks, but now it is okay. My only concern now is the vaginal discharge and the itching.
