My cat has a sixth sense??

Okay so we have a cat named molly. Super bitchy girl and never ever wants to cuddle more than 5 minutes and never with me. Only my SO. The last couple of days she is sleeping on my pillow and laying in my lap and staying there for hours. I have no idea what is up. Could it be in pregnant and she knows it?! LOL, kind of far out but I've heard it before!
