How does being on the pill affect the results of a home pregnancy test? Can it cause a false positive?
Being on the pill will not affect the results of a pregnancy test. Home pregnancy tests are most effective when taken one week after a missed period. If a pill is taken every day at approximately the same time (within two hours), until the pack is finished, and the woman taking the pill is not sick with vomiting or diarrhoea, and has not taken any antibiotics, it is unlikely she would become pregnant. If you have taken a home pregnancy test and it read positive, it is important to visit a Health Care Provider and have a lab based pregnancy test done.
