Can taking spironolactone cause a false reading on a pregnancy test, specifically a serum qualitative blood pregnancy test? Also, how reliable are pregnancy tests? I had sex in January, took Plan B, and have had two small bleedings during my sugar pill week. I've taken multiple home pregnancy tests (HPT) and had both urine and blood tests at the doctor, all of which were negative. I am taking spironolactone and want to ease my mind about potential pregnancy.

Spironolactone will not affect the results of a pregnancy test, whether it's a urine or blood test. ...
