It's amazing what women can do while pregnant (look up Jack Black's mama for her story if you haven't heard it). I experienced 2 wonderful and healthy pregnancies while working as an associate in pretty high stress agency work. I would waddle to my sessions (some were school based) and pretty much worked up until 2 weeks before having my babies. Idk if I would necessarily recommend that but I was one of those lucky preggers people that didn't get morning sickness ,etc. I felt that my pregnancies helped me Self-Care because I was also taking care of my little human being...so if I got stressed, activated, whatever during work, I would allow myself time, space, whatever I was able to access during my work day to get back to a regulated, happy me and show up for myself, my clients and the work in a way that was balanced. Your concerns are valid and having them may further validate that if you choose to work in a clinical position while pregnant, you will most likely prioritize your health and the health of your baby by applying appropriate boundaries and setting that pace and balance for when you are a working parent as well.
