I've been using the patch ever since I started my period. This time though I had my period and then I put my first patch on to start a new 3 week cycle. However, I'm still having pretty strong cramps on the second day of my first week. My period also started 3 days late. Will this go away or do I need to see a doctor? Do I take it off for a few days and just restart? I haven't had sex in over a week.
