A little about my situation I was going on vacation and my period was about to start a few days into it. I decided to take the patch evra birth control to delay my period. I wore it for 3 days and it gave me major cramps and I didnt want to wear it anymore so I took it off. Anyways it's been 3 days with it off and still no period I figured wearing the patch would delay it and mess up my schedule a bit but just wondering a range of when I should expect it? A little side note I am sexually active and don't use any form of bc.
