Just curious and thought this would be a good place to ask - did your doctor give you a specific heart rate to stay under during your workouts? I try to go to the gym 2 to 3 times a week and so far have just been sticking to the elliptical or a brisk walk on the treadmill in addition to weights (a little lighter but more reps then before the BFP). I sometimes run/jog and have done kickboxing classes etc. but right now do not have the energy for that at all. I can ask at my appointment, but it is not for a few weeks yet.
