What would you do if you were me ?

I will be done with my associates degree in medical assisting at the end of October, but  during that month I have to do Externship which will be 180 hours that I have to complete . The problem is I'm pregnant and by that time I will be about 7 or 8 months. I talked to my counselor and she said I can still do it but it will depend on me how I'm feeling and what my doctor says. Other than that I will have to do it after I have my baby but after talking to my mom about this she left me thinking. She told me to do it before baby is born because after it will be hard ( I also have a year old ). Now I don't know what to do.
