doing and not doing

I'm pregnant. But I feel I want to do a lot of things. Actually, I'm a bit worried if I'm too active. Lost a child once due to unknown cause. I really want this baby, and at the same time I have a lot of things I want to do. A lot of things I want to achieve. But I have to restrain myself because I have to take care of my body so that I won't be worn out. But then I have to plan for the things I can do....... Hmmmm suggestionss pleaseeeee....
