I have been using OrthoEvra (the patch) for like a year and I recently switched to Nuvaring just to try it and it kept falling out when I had sex and so I decided to go back to the patch so after the first week of Nuvaring I took it out and put the patch back on so it was the second patch. And I decided I would change the patch like normal and then take it off at the end and just have an extra patch left over. I had unprotected sex the second day I put the patch back on but I have been on BC for like 3 years now so was I protected? I just couldn't stand Nuvaring any longer. Please help me.
