Baby blues

Hello I'm 40 weeks and 1 day and this morning I woke up emotional. This pregnancy has been really difficult for me because the father of my baby has been acting like a jerk with me and I been strong holding all his meanness inside me but today I couldn't hold it I been feeling sad, empty, and weird. I think is because of him and also because my baby is not born yet. I don't know if his is normal ?
