Mixed feelings

I am almost 37 weeks pregnant with my second child. I have stayed at home with my son since he was born. He is almost 3 years old and I just have loved being with him. He’s a mommas boy and I sure have love being his momma. I have this guilt because I know in the next couple of weeks things will change dramatically for him. I am nervous and

excited. I’ve been crying for the past few days and idk why. I’m scared. I don’t even know the gender of this baby. Anyone else just in a crazy state of emotions?
