Look, here's an answer that's helpful, instead of judging you - you are concerned about this abortion, which means you will regret it and feel really, really bad after you have it...right now you are worried about other things and you don't realize how bad you'll feel. Take it from me - same thing happened to me. So many people would give anything to have a child and they can't. So consider having it and giving it up for adoption to someone who really really wants a baby and has been waiting so long...or just have the child. After that, don't date anyone who won't use a condom. Believe me, the psychological effects of abortion will hurt you worse than having the kid. People who want to adopt will help you through this. I wish someone had given me this advice.
If you can decide you really really want the abortion, then do it, but if you're on the fence, hang in there.
