Should I Keep It?!

I'm a 22 year old filmmaker with my entire career ahead of me. I'm 4 weeks pregnant and I always said if I ever got pregnant before the age of 27 I would abort it because my career is too important. Unfortunately, that decision has become increasingly difficult for me. The father and I met a few years ago; although, we were only friends at the time and recently reconnected a little over a month ago (I know...the timing's crazy) but we really see ourselves having a future. He knows about the baby and says he'll support me either way. I take comfort knowing he'll be a good father and he's financially stable. We've explored all options and occasionally joke about being a big happy family... but then there's MY family (strict Christians who will be so devastated and disappointed) and still MY CAREER (which is only just beginning). I don't know what I should do... I don't know if I want an abortion but I don't know if I want to keep it, either, because this will hinder the career I've worked so hard to build and kill my family. The anxiety is killing me.. Please help!
