I don't feel attractive

Anyone else feel like they just don't look attractive? Since the pregnancy I have not been doing make up hair etc and when I do try I just don't feel as pretty. I'm not far along but I just fear my SO is going to think I am not attractive and feel forced to be with me because of the baby. He always tells me I'm beautiful but now that a baby is on the way I am fearful that will be the premise of our relationship instead of love and attraction to each other.
