Dog hates me

So I know it's common for some dogs to get real overprotective or lovey when we get pregnant due to hormones. But has anyone had their dog be scared of/hate you? One of mine runs as soon as I walk into the room when before she was my best friend. It makes me sad and I want to know it she will go back to normal once it's all over. Thanks!

Picture of her because she's so damn pretty!
