Answered there. 50-50. No one can give you a better estimate. You DO stand an excellent chance of being pregnant via not using birth control (pullout does NOT count) but you also stand an excellent chance of NOT being pregnant because you are still nursing and had a baby a couple of months ago.
All you can do now is wait a couple of weeks and test. And if you are NOT and don't want to be pregnant... tell hubby there will be no repeats.
