Is my wife demanding?

Hello everyone. I have a question. My wife is a few weeks pregnant, first trimester. So, being the caring and loveable husband.. I cared for my wife's needs. But I realized, even the smallest things.. she asked me to do it. I don't mind helping her and taking care of her but is she taking advantage of me just because she's on her first trimester? Please help me understand, is this normal for the wife's during first trimester? #firstbaby #advicepls
