Pregnant & work

So how many of you ladies are expecting & work in a doctors office/hospital setting? I'm just curious because I go to school for medical assisting and I graduate in November, so I'll be doing an externship in October when I'm roughly 25-30 weeks pregnant and I just don't want it to effect my externship. I'm due January 1st and I want to stay on track with school so I graduate 2 months before I'm due which is perfect.
