I've been sort of in your position. I did get pregnant about a year ago and chose not to keep it. It was the right decision for me, my family, my relationship with my boyfriend, and for the baby. Everyone feels differently about babies and abortion. It's important you really soul-search on this one and find out how you truly feel, and I think coming here to this forum is a good step to take. So, congrats!
You really just have to do what's right. Maybe seek a spiritual adviser, a counselor, or even just a friend. I will say this: don't have an abortion if you think at all that you'd regret it later. Some people take the quick way out and then regret it--either for moral reasons or because they end up never having children, and I'm sure that's a horrible, horrible feeling. Also, some people have children and then might resent the child, or resent themselves for not being the 'perfect' parent.
Good luck!!! Much love to you!
