Any ideas about the pill??

Does anyone know how long your body can take to get pregnant when you come off the pill? I know it's different for everybody, but what's the average? 
Because I've missed my pill for two weeks straight once and I was fine, and I've only just come off it, and have been off it for a whole month now. My SO and I had unprotected sex a week ago now and I was just wondering if there's a high chance of me getting pregnant from that?
