I'm 16 & pregnant 17 in September this is my senior year

I'm currently 10 weeks and still haven't decided if I want to have an abortion / adoption or Keep the baby the father knows and he wasn't happy at first we agreed on abortion but I just couldn't do it I don't feel very connected to the baby but I feel like it's because my mom wants me to have an abortion and I'm just scared I'm not sure what to do but my mom says I have to have an abortion Monday or I have to go live with my father I really need some help making this decision
