Animals flocking to you because of pregnancy? I can't tell!

My family has 6 animals (3 cats, 3 dogs). When no one else is home they always are always following me around. I heard that during pregnancy animals will become closer to you. I'm almost 28 weeks and I can't tell if my pets know I'm pregnant or not because they're always with me anyways. How are your pets taking your pregnancy?
