I am 7 weeks pregnant..should i have an abortion?

I am 17, turning 18 in the fall. I am 7 weeks pregnant and everyone wants me to abort. My boyfriend of 3 yrs said he would support me regardless. I am having second thoughts because my mom scheduled an abortion appointment TOMORROW. But Idk if I want that. Should I struggle for my baby bc I want it or should I wait until I am done with college to provide a more stable life? I am so afraid I will make the wrong choice...should I keep the baby or is an abortion through better choice. Please help me.
