Cats around pregnancy

Is it just me or is my cat really starting to become closer to me. He’s always trying to lay on me or my tummy now that I’m pregnant ? Does he know ??? I wonder ? Anyone’s else’s cat do this ? I’m concerned about these old wives tales I’ve been hearing about how cats cover the babies mouths? How are cats with newborns usually ? I don’t want to give rid of my baby Draco 😔😔 he’s currently laying on my tummy! Big ol baby!!!!
