The reason why your whole body aches may be due to the increase of lactic acid in your body. If so, that's no problem, because you do aerobics to exercise all joints of your body. I think this is more likely. But I think it's good for you to have a check. It is not recommended that you do aerobic exercise, because of the large amount of activity and weakness after abortion. If you do a lot of activities, you may faint. You can jog, but don't last too long. You can combine jogging with walking, or you can do brisk walking. I wish you a speedy recovery.
