How to apply Evra patch for menstrual disorders?

Hi, More than a month ago I completed the hormonal treatment of Evra patches after discontinuation I had stable for a week at the moment I do not have a period. I was doing a pregnancy test came out negative I contacted my gynecologist I said in what problem I am currently taking a remedy 💊o called OVARIN but rather not help you doctor said that if the drug does not work to glue the patch Evra just wonder how to do it or stick the patch and at the time of getting the period peel off or after a week peel off and stick the next and so to the end of the package. Please advise me Regards.
