If you are wondering about damage, this is very subjective. A properly cooled computer will not suffer any ill effects to it's processor or other electrical components from heavy use. However if it is overclocked, poorly cooled, or experiencing 'dirty power' components may last less time.
A processor or memory chip set to a lower voltage and/or frequency will last longer.
Turning a computer on, however, sends a burst of electrical charge that causes much more fatigue than simply leaving it on- Each time a PC turns on, it is roughly equivalent to 30 hours of use. You can cause a computer to fail within weeks by rapidly cycling the power on and off. Sometimes even days!
Fans that are constantly running may also age or jam, due to the moving parts.
Harddrives which are in use for this time will age, due to the motor and other moving parts.
Solid State, Flash, and NAND drives will also age if they are being written to, and can fail rapidly under heavy use.
Generally, most people put their computer into Sleep or Standby modes if they are stepping away for a short time (10-120 minutes), and turn it off or Hibernate if they're leaving for a while.

It had been thought in the past that the low-level electromagnetic fields produced by computer monitors could be harmful, and could specifically cause miscarriage or harm to your unborn baby. However, repeated studies have shown that there is no risk associated with these electromagnetic fields. The biggest risk in computer use while pregnant is the risk of spending too much time at once in front of the computer, because your body needs to have regular movement. In addition, while you are pregnant sitting for long periods of time can become uncomfortable and aggravate any problems you may have, such as sciatica. If you must spend extended periods in front of the computer, take frequent brief breaks to walk, stretch, and move. - Its ok to use a computer while your pregnant, the computer isn't going to hurt anything.
