Sign of pregnancy!?!?!?

Brittany • Happily married & diagnosed with PCOS. Baby dust much needed!
Anyone experience a change in your animals behavior with your success story or even before you realized you were pregnant? 
I only ask cause my dog will not leave my side. She keeps laying all over me and won't let my husband touch me. My husky is never like this & is only cuddly when getting full attention or she's gone lol.
