My furry baby is acting out 😢😠

I'm feel so frustrated and stressed out with my 6 year old English Bulldog. She is starting to pee in the house and on her bed and laying on it. She has the house smelling like pee and she always smells now. She obviously never did this before and people keep telling me that she is just doing it for attention and is probably sensing change. So my boyfriend I started to give her extra attention and play with her more, but she is still doing it!! What am I suppose to when the baby comes???? I don't want to give her up, but I might.
