Pregnancy hormones ?

Hey ladies I’m almost 20 weeks pregnant and my question is did you ever really dislike someone during your pregnancy ? I heavily dislike my FIL idk why but whenever he comes near or says something it irks me so bad I can’t even be sitting where he is because I will feel super uncomfortable he try’s to talk to me and of course I’m grown so I have to be subtle but sometimes I just wanna leave because I can’t stand being around him he has said a few snarky remarks during my pregnancy but it’s not something I’d normally care about but anyway does this feeling go away ? is it normal?
