Yes, menstruation can sometimes affect a urine sample by potentially contaminating it with blood, which may impact test results. It is best to inform the healthcare provider if you are menstruating before providing a urine sample so they can interpret the results accordingly.

Not sure I understand your question. Anything that gets accidentally added to a sample substance is a contamination. As such, gunpowder can contaminate a blood sample. But it is unusual to handle gun Powder, so how gunpowder would get into a blood sample is beyond me.

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.

Yes, it will contaminate the sample causing them to mark it as Unusable. But doing so can be seen as tampering your urinalysis and get you in big trouble. If its just a home test it wont help you much.
Both will show in a urine sample if tests are done to look for those drugs.
The best time of day for a proper urine sample is first thing in the morning. This is because the urine is more concentrated then.
