17 pregnant

I’m 17 and find out I’m 4-6 weeks pregnant I already know what I’m going to do ( abortion ) but I still can’t believe I’m pregnant like I’m in dial, the father knows and doesn’t want me to keep it , but I can’t help to think what if i abort it and it’s a mistake. I’m currently having colleges look at me for scholarships and everything and this will be a set back bc this is always what I had in mind, high school — and track in college if that doesn’t work than something in the graphic design field. But what if I don’t like college or doing track anymore, I would’ve had an abortion for no reason , I’m telling my mom this week and she already told me that she’ll be damn if I get pregnant and she’ll make me have an abortion. My whole family will yell at me and throw it in my face for the rest of my life. Can anyone give me any advice and how they mad there decision
