Is it possible for me to get a free abortion? (Pro-lifers don't answer PLEASE!)?

So I just turned 17 my boyfriend is 18. We had unprotected sex a couple weeks back and I am 100% positive I'm pregnant. I thought about this long and hard and realized I couldn't have my baby. But now Im trying to spare my mom the disappointment of me being pregnant. I don't have the heart to tell her. So I'm wondering if I can get an abortion without my parents consent in California? Also I really don't want to spend 400+$ for an abortion, is there any way I can get it for little or no cost? Thank you, and please don't judge me you don't know me enough to penalize me, and I'm sure you won't understand my circumstances.
