Abortion clinics and self abortions?

Please don't judge me. How old do you have to be to get an abortion? I'm 14, and I think I might be pregnant. I've only had sex with two guys. All together 5 times. But the last time I missed my period. We used a condom but I'm freaking out. Do your parents have to know? And how much does it cot to get an abortion? And what are some ways to give yourself one, and what are the risk of giving yourself one? Thank you.
