Weird pet behavior

Ari
I've heard of dogs "sensing" pregnancies and being super needy but mine is doing the opposite! She still greets me when I come home but she no longer wants to cuddle. I hope I'm not stressing her out. I try to give her extra attention and she willingly accepts scratches and kisses but no cuddles...☹ 
Anyone else experiencing weird pet behavior? She's a mini poodle
