Restarting familiar exercise when pregnant

[cloudjumper]

I am just over 13 weeks pregnant and have not been able to do any exercise whatsoever since I found out, due to sickness and tiredness. Before that, I used to go running and do Bodypump in the gym, about 2-3 classes per week.

Now that I am starting to feel better and my energy is slowly coming back, I would love to re-start exercising. But I'm a bit concerned that I have not done anything for nearly 3 months now. Will it be OK to re-start exercise that I was doing regularly before falling pg? I don't think I'll be taking up running again, due to some hip issues, but I'd really like to do Bodypump (did it when pg with DS), obviously with all necessary precautions. Will it be OK, in spite of the long break?
