Spotting again.

Annie
I am typical very regular 28 day cycles. I had a cyst burst 5 months ago. This past period was 4 days late lasted 9 days (typically 4-5 days) and now 2 days after the bleeding stopped I am spotting light red again. Any ideas on what could be going on? Also some very light cramping that could just be in my head since I am kind of freaking out.
