Yes, you can fail to clean your genital area when you urinate, which might cause bacteria that was residing on the skin to fall into the urine sample. The doctors wouldn't be able to tell whether the bacteria originated from, say - your hands, or your urinary tract.
The urine needs to be completely clean and have no contact with anything other than the urinary tract and whatever is being used to collect it.
if its not urine than its contaminated isn't it...
It is very common for a person who is menstruating to contaminate a urine sample. Of course, contaminated urine samples are very common in general.

Surely you are SUPPOSED to urinate on the area anyway. YOu need to clarify the question.
Not directly. It might cause "spotting" - small amounts of blood from inside the womb that sometimes appears between periods and this might contaminate a urine sample (i.e. a false positive for haematuria - blood in the urine). A properly conducted mid-stream urine test should prevent contamination of the urine by uterine blood.
