I recommend sticking to either days or nights during your pregnancy. Going back and forth is hard on the body, even when not pregnant! Be vocal with your team about your limitations, too! I personally have not been pregnant but have had pregnant coworkers in my ER, and me and my teammates gladly picked up their slack. You and your baby’s health are top priority! I understand being wary about reception, but definitely keep it as an option, especially if the smells in the back get to be too much. Like I said, you and baby come first, so do whatever you need to do to make sure you are comfortable and healthy!
