xulane patch help!

Helen • 23. Staying gold.
This is my first month on the patch since being off birth control for a few months. I started the first day of my period last month on the 29th of September and it last 6 days. My partner and I had unprotected sex on the 9th. I am now on my patch free week since taking my patch off on Thursday the 20th I started having cramps last night and super light bleeding this morning. Is this normal?
