Pregnant or not ?
Taking a pill a few hours late only minimally increases the risk. (If women always got pregnant when they missed a pill, it would be sold as a fertility drug.)
Extremely unlikely especially if you are using a combination pill. The combination pill is extremely effective even when the time it is taken isn't perfect every day. Even on the mini pill, it would still be unlikely that you would immediately ovulate in time for the sperm to still reach the egg. It isn't like you ovulate the moment you miss the pill.
