Dog aggressive while pregnant

So I’ve seen posts of other people saying how loving their animals are while you’re pregnant, but my dog is the opposite.

She’s not aggressive towards me, just towards my other dog or cat if they get near me. And it just started this week! She’s been chill during other pregnancies and at the beginning of this one, just something about this week she’s not happy.

Should I be worried? Think it’s just a phase?
