Do you have a family doctor? If so, please call them. They will be able to give you more information about abortion, where to get one safely, how much it will cost, and the health issues that may be associated with an abortion.
If your doctor WILL NOT do this (some won't because of personal belief) you can call a pregnancy hotline and get the name of a doctor that will.
You have the right to be counseled on ALL of your options before making your choice, remember. I know all too well the panic that hits when you find out you're pregnant and don't want to be. Make sure you're making your decision with a clear head, not in panic.
And yeah... I agree with a previous poster: let the father know that child support of one year is going to be a heck of a lot more than coughing up the money NOW for an abortion.
Good luck to you. I've been where you are now, and it's not a fun place to be. If you need to talk, let me know.
