What’s wrong w/ me?

Ok, so I’m currently about 10 weeks pregnant with my second child and my first child is 5 years old. Idk if it’s because of my hormones or what, but she’s been extremely annoying to me lately. Just hearing her say “mommy” irritates tf outta me! Has anyone else been annoyed by their other child/children more than usual during a pregnancy? I still love my baby very much, we still play around, laugh, act goofy, hang out, hugs & kisses, etc. Nothing has changed besides the fact that sometimes, she aggravates the shit out of me a little more than usual. I feel so bad when I tell her to get out my room but she’s always yelling & screaming when she plays & that annoys me SO much.
