Hello, Thanks for letting us know your health concern. I have gone through your query and would like to offer you some suggestions. If you are going to have a routine urinalysis and blood counts, the use of the emergency pill cannot be detected. The hormone excretion can be detected only by testing for progesterone and even then cannot be discriminated from the natural hormone unless tested for specific compounds. Intercourse cannot be detected through blood and urine tests. It is detected through a vaginal exam and detection of sperms. Hope this helps.
