Cats not happy

So my boyfriend had a cat when we got together. We just started really bonding when I found out

We are expecting. She’s not having it😂 she is peeing on my side of the bed, attacking me, and even getting out which is so unlike her she used to be afraid of outside. I don’t know what to do at this point. We are trying to move out and I know that’s gonna make it 10x worst. Anyone else deal with this. Someone told me fixing her would help. I plan on doing it before we leave anyways but is there anything else in case that doesn’t help. I feel bad she’s so stressed but I have to worry about how she’s gonna react to a baby now. Just really looking for advice
