My cat is attached to my hip help

Nicole • Carried my baby girl for 38 weeks had a csection and got to meet her on 12/23/2015 happy FTM 💜💚💙🎀
Hey lady's this is my cat Gemma she's always been a Mommys girl but since I've became pregnant she's been up my butt always wants to be with me fallows me everywhere even outside when I'm in the pool she wants out to sit on the deck to watch me. I know she senses that I'm pregnant but why is up my ass?? When she sleeps she has to be touching or laying on me my fiancée said he has seen her looking at me while I sleep creepy right?? I would never get rid of her she's a great cat she's potty trained so no litter box and she's my world till my little bundle gets here then I'll have two Babies. Any ways does anyone else have this situation with there cats or dogs??
