I have been using the patch for over two years. I have had regular periods during the patch free week. I change my patch every sunday and today 9th November I should change from my second patch to my third week patch but I have woken up to having started my periods. Shall i continue using the patch as per usual? My patch is applied properly - early periods maybe due to extreme weather change and weak body? If so, do I change my patch cycle if my period begins to start during my second patch week and not during my patch free week?
