I just found out my Girlfriend is pregnant

I dont know what to do right now. Im still in School and I dont know if I can handle a baby. She once said she was open for an abortion, but that was at the beginning of our relationship. We haven‘t had the chance to talk about that seriously yet. Im not ready for this. Im only 18 years old and I have my whole life in front of me. I won‘t be able to financially support a child until 4 years from now. Im not planning to leave her if she decides to keep it. I will he there for the child but I dont want to have a child. We always used protection and I don‘t know how it happened.

I just needed to post this somewhere as I don’t feel comfortable talking to anybody about this at the moment.
