Yes you can do all the above..there would be no harm to the baby.i asked my dr this when i was pregnant she said not a problem,as for your other posting,spotting is classed as just a little perhaps blood or brown when you wipe.this is called old blood.best of luck..
You can dance and jump around in early pregnancy but obviously once you get further along your not supposed to jump around anymore since your center of gravity is thrown and you could fall over. However light exercising is recommended throughout your pregnancy.
