Am I bad?

So I've loved kids since I was 13. I'm really good at looking after them and showering them with love and gifts. I have a lot of nieces and nephews who I love dearly. But I am now 10 weeks pregnant and for some reason all kids are starting to really annoy me. Like I'll hear a kid enter the room and I tense up and roll my eyes like ugh go away.

I really hope that I'm back to normal by the time I have my little one. I feel really guilty because it's like an involuntary reaction and I just feel immediate disgust and annoyance at all kids now.
