My mom just found out I'm almost 6 months pregnant. And she wants me to do the stupidest thing...?

She wants me to lie to planned parent hood and say im 3 months so i could get an abortion. i told her im not about to liee to them because i can feel the baby moving inside and i dont want to hurt my body like that. And i told her that i cant do that because its tooo late but she thinks im making an excuse to keep the baby. what do i do? btw im 16.
