I am a 16 year old female, not sure what my exact height or wright is but I'm sure I'm abot 5'2, and I think just under 8 stone. I have been to the doctors twice about my urine and both times been prescribed with an antibiotic for 3 days but they haven't worked, my urine is really smelly, cloudy and sometimes is a horrible colour and leaves marks on my underwear. Can you please give me suggestions ??
