Patch has been on for more 10 days! Help!

Alanis

So I had started back at Patch 1 of my cycle, but found out I ran out of patches, the patches didn’t come until today, Saturday, but my patch change day is Wednesday. So I left the patch on until today and then switched it as soon as I got the new ones. I thought I was in the clear, but now I’m bleeding, like beginning of my period bleeding. Should I be worried or is this just a side effect? Please help! :(
