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.
