If you have a normal healthy pregnancy you can go on with your ordinary life. If you strain yourself you will feel it before you miscarry. The longer the pregnancy goes there are things you will not be able to do so it solves itself.
It's a myth that exercise leads to miscarriage:
"Too much exercise can cause miscarriage."
Many women avoid exercise during pregnancy out of fear the baby may be harmed. Exercise is actually very good for you and the baby. You should always ask your doctor about your particular routine and follow some safety rules, such as staying hydrated and not overdoing it. Again, if there are complications, you may be told to take it easy. But unless the pregnancy is already threatened, there is no harm in exercise.
