ok so I've been ttc

And if this month it doesn't work it'll be my 5 th month trying to conceive. Ok so my question is why was my tias dog barking and growling at me. Then when I looked at him then he started crying softly then started growling. He's also always sniffing me for some reason. Do you think he can sense if I'm pregnant I know it's not accurate I'm testing on the 24 th.
