am I going to be a bad mom?

I'm currently 9 months pregnant. I normally love other people's kids, but since I've been pregnant I've been finding that I'm kind of annoyed by them. I'm worried this is a bad sign that I'm going to be annoyed by my own kids, or impatient with them, but I'm hoping it's different with your own children? Thoughts about this? Does this make me a bad Mom-to-be?
