If you don't want to have a baby go to the nearest planned parenthood immediately. Tell them your situation, have an ultrasound and find out what your options are. Listen to all of them. Ignore what everyone around you says and listen to what you want to do. Think about what is best for you. If you want to have an abortion, they can help you, even if you're farther along than you expect but don't wait, go asap and figure this out. Putting it off will only cause more problems, cost more money and put you in a worse situation.
If you feel you're not ready, you should either go through with the pregnancy and give it up for adoption, or talk to your partner/the father and abort your child. Milly X
