HELP!! BIRTHCONTROL AND BLOOD

Jen
I am on the patch. I remove it on Tuesday Night and forgot to put a new one back on until Friday Night. That same night I had unprotected sex. Should I be okay or do I have to take a Plan B pill?
And the next morning I start bleeding.
I couldn’t be in my period since I just had it at the being of the month, right? I had in the 1st week of Jan and latest about 4/5 days. And it’s the 19 today. What should I do?
