Anywhere from 5 -30 minutes; actually for pregnancies that are still in the first trimester the actual abortion procedure takes 5-10 minutes. For pregnancies in the second trimester the abortion procedure will last anywhere from 15 – 30 minutes, all dependent on the gestation period. But it all depends on which abortion procedure you have. In some cases you could be at the clinic anything from a couple of hours up to around 7 hours. This will be discussed during your consultation.
