She is pregnant with a child to take care of, without knowing your situation, my first guess is she is feeling overwhelmed and you going out makes her feel abandoned to deal with the things she is dealing with. These feelings could be rational and based on the fact that you don't do as much as you could/should be doing or if you really are doing your fair share, her feelings might be more on the irrational side. Either way, her feelings are real to her and should not be discounted, especially if she is being irrational/hormonal because she is less equipped emotionally to deal with the situation.

Something to keep in mind, I saw a study in class yesterday that showed that men in relationships where both people work outside the home, typically do up to 30% less when taking care of the home and still think they are 'doing their share'.
