Hello sir I had sex with a girl and since then I have urinary tract infection I don't know if infection is because of sex because I had uti before also my urine is dark cloudy and smelly I had blood reports of uti but doctor said they are normal but the treatment he suggested do not have any result I had taken a course of 5 days. When I take tablet then my urine looks clean but after the day I stops taking antibiotic it appears again please doctor suggest something. Do I have any std?
