Please don't! The world will be better with your baby in it.
Regardless of the circumstance you are in, being pregnant means you are carrying a real, live baby! How incredible! Your baby deserves a chance at life. You deserve to live without the guilt and regret that are close companions of those who abort. Just because your baby was unexecpected, does not mean it has to be unwanted. There can be a new and wonderful future for both of you!
