Pregnancy? An "easy thing"? Are you kidding me?
I would never do this personally, but if you are not ready to have a child, close your legs, stop having unprotected sex, and either get an abortion, or put the baby up for adoption.
Personally, I think you should have an abortion. I am completely against this, don't get me wrong, but you will NOT be taking care of your baby with your eating habits, etc. You don't deserve to have the gift of being pregnant.
You are immature, selfish, and ready to ruin an innocent human beings life.
Think a little before making such a life changing act.
