I am cari, and although I have not had an abortion very young, I have had 3 after the age of 18, I also work in an abortion clinic.
Often, teens have abortions later than adult women do, mostly because they have to find ways to obtain an abortion in the first place. Teens also have irregular cycles, because their bodies have not had time to regulate, so this can also push an abortion later than their more regular adult counterparts.
At my clinic women are put to sleep so they feel no pain during their abortion, and many clinics offer this, I hope yours did to!
I see nothing wrong with an aboriton at 5 months, I just am sorry you did not find out earlier when it might have been easier on you. You are not an oddity, but not many women will admit to 2nd term abortions, because of the stigma associated.
I don't think you are a bad person, and I am glad you came to share so we can support you!
