Birth control question!

Hey ladies,
I regularly take a birth control pill. I don't remember dates, but after my placebo week, I didn't refill my prescription. So I had an extra 9 days off the pill. On day 7, (day fourteen if you count the placebo week), I had unprotected sex once. Two days later I started my pills again.

What is the likelihood of getting pregnant/possible complications of being on the pill now?

Note: totally wouldn't mind being pregnant, so I'm not worried if I am
