I think you will appreciate my comment because I'm working full time as a RN, going to school for FNP (half way done), and am currently 25 weeks pregnant! At my hospital, we work 7 shifts/ 2 week pay period. I've been taking 1-2 classes (theory) per semester, including during my 1st and 2nd trimester. I even think of taking 1 course during Summer school which ends when I'll be 37 weeks pregnant :-)
So far, I did Advanced Patho, Advanced pharm, advanced health assessment (while pregnant), bioethics, research, spiritual care (required at my school), and advanced Roles.
I have 5 more clinical courses which I plan to finish in 2 years. So, yes, it's doable if you're type A like me, over-energized, can enjoy an semi- easy pregnany, and have a supportive husband. We have a housekeeper who comes twice a month. My husband does laundry and grocery. I cook 1-3 times/ week and we do take out when I can't. I work night shift and my husband works 7am- 330 pm so we have dinner like at 5 pm. I'm off every other weekend so we plan our going outs accordingly. After my son is born, we plan to have family help for 3 months then hire a live-in babysitter. I will also take 1-2 semesters off as my baby dues in August. Hope that helps!!!!
