Most abortions occur if you choose to have one during the first trimester which is up through twelve weeks of pregnancy. About 90 percent occur during this time. The procedure itself is called suction aspiration and is seven-ten times safer then regular child birth and lasts only five minutes. The surgery is a low risk complication surgery and you should be able to return to normal in a few days.
If you choose and wait to have an abortion during the second trimester which is from 13-24 weeks, then you are putting yourself in a much greater risk. The surgery is called dilation and evacuation. This is much more dangerous because you have given the baby more time to develop and it will be more complicated to remove and could put yourself in danger. Now insted of a five minute operation, it can now take up to two-three days to remove the baby and requires a longer stay in the hospital or medical facility
