Nervous

I am 38w5d and I am SO nervous. Not that I won't have an amazing baby, but that I am going to do something wrong. What if I don't notice signs of labor? What if I'm leaking amniotic fluid and don't realize it? Every week my OBGYN asks if I'm having contractions and I tell her I'm not sure. I'm still working full time as an RN, and I don't know when I should say enough is enough and take off work. I just don't want to do something wrong and put my baby at risk.
