I ve been on Ortha overa birth control patch for my 3rd month... & well I was 12 hours late putting on a patch after my patch free week... is there any chance that could have decreased effectiveness? Like should I have to use backup protection for a week? I normaly change my patch Sunday morning & I didn t put the new one on until late Sunday night....I did have unprotected sex Thursday evening & according to my period tracker that I ve used for over a year indicates I m fertile... I hope you can answer my question!
