Spotting or a problem??

So this is my 1st time every skipping a period on the pill. The 1st skip went great, the. When the 2nd pack ended I skipped period #2 with the 3rd pack of pills and after the 1st week of those pills (then having sex) I noticed bleeding. It’s not really heavy, I can tell it’s spotting, but it’s been 12 days and it hasn’t stopped. Should I be worried?? Is this normal?? Should I stop my pack and give my body a break then start up again? Has anyone else experienced anything like this??
