For the majority of women, if you have missed your period for one week then it is a good time to test to see if you are pregnant using a urine pregnancy test kit. Some women have very irregular periods in which their menstrual cycles are more than one month long. For these cases, weekly urine pregnancy testing after a five week delay may be helpful as it may not test positive after 5 weeks delay. If the urine pregnancy tests are still negative, a more accurate way may be to test for BHCG levels (pregnancy hormones) in the blood.
