What Not To Do While Pregnant Here are some things to try and avoid doing: a)changing cat litter b)lifting and carrying heavy weights (groceries, children etc.) c)Leaning foward (spreading beds, vacuuming etc.) d)standing for long periods of time (while ironing, washing dishes etc.) d)balancing (climbing ladders, cycling in late days of pregnancy) e)I have heard also that exposing your bare belly to the sun for a long period of time may cause damage to the unborn baby f)try not to take ANY medicines unless tolf to do so by a doctor g)don't use jacuzzis, saunas or anything like this, they can make your body too hot for the baby, maybe a luke warm bath for 5 to 10 minutes if you feel like you need a little rest.
