I have continued my normal workout routine so far at 28 weeks. I had no nausea or fatigue, so have been able to continue as normal. My doc told me exercise as tolerated, modify T make things more comfortable as required. I usually workout 5 days/week. Something different everyday. Typical week is one day of each of the following: yoga, running, T 25 or easier insanity video, hike, elliptical/weights/gym workout.
