I had been working in the neuro ICU for 2 yrs when I got pregnant. My son is 5 weeks old now and I worked all the way up to a week before I delivered. I had a nomal pregnancy besides gestational diabetes. I was fine all the way up to 36/37 weeks then I became miserable. I was exhausted. It's hard enough getting around during your 8/9th month then on top of that doing 12s, turning,pulling, and bathing patients, roadtrips were difficult, along with the other nursing duties. I felt bad always asking for help, but I worked with a wonderful team of nurses that was willing to be my wingman. If your interested in getting the experience I'd go for it. It may be difficult, but I think any nursing job will be physically demanding. I wish I wouldn't have pushed myself into doing 12s and did 8s the last month. Congrats and good luck.
