I unintentionally became pregnant with my second child just 6 months after my first was born. (Considering that I was 41 and all statistics led me to believe that the odds of my carrying a second (healthy) child to term were those of being hit by lightning, I was happily shocked.) Yes, you could be pregnant again, but considering you are taking Nor-QD, it seems unlikely.
