If you have a 2 year old kid and your 17, can you legally leave your guardians place without them calling the cops?

I'm 17 I have a 2 year old son with my boyfriend he is 17 he turns 18 in October. I had found out I was pregnant again and my mom kicked me out and told my boyfriend to come get me I stayed with him for about 3 days. My mom came and got me and made me stay with my dad so I'm in Pasadena at the moment I don't want to be here my father isn't on my birth certificate. I want to know if I leave my fathers house and move with my boyfriend without my mom being able to call the cops.
