Cat senses I'm pregnant 😭

Rebecca • Mommy to a beautiful baby girl born October 24,2017 💗
So lately my cat has been acting weird.. pushing his butt against me and rubbing against my stomach. Well today he peed on my bed 🙄 he's 8 years old and never ONCE has ever peed on beds ever but this is my first baby and I'm 7 weeks and 4 days along and now he's peeing on my bed! Anyone else have this happen? I googled it and a lot of people go through this with their cats too ☹️ also, it's not a hatred toward me cause he's more cuddly to me than anything but I don't think he likes the idea of the baby! He's also fixed.
