Anyone's fur babies sensing pregnancy??

Katie
I work from home, so my pup and I spend a lot of time together anyway and are very close, but the past couple of weeks she is my absolute shadow, and wants to sit on my lap or lean on my shoulder almost constantly. 
My poor husband is getting jealous bc all she seems to want to do is cuddle with me!
Anyone else's pup acting this way? I have to think she knows I'm going to have a litter 😂😂😂
