You didn't explain that, it was asked why you were thinking of abortion when you do not believe in it. You didn't state explicitly your reasons for considering abortion.
How have your parents reacted to the pregnancy?
How has the father reacted? (i know you said he was a p***k on the other thread but he does need to grow up, either way) are you still together?
Have you contacted any pregnancy centres/helplines? If you can find netural ones (i can help if you're in my area of the world, uk) then you'll be able to assess all of your options either way.
You do need to think about this seriously, neither having an abortion or having a baby will be easy.
