starting up BF again, is it possible?

I quit BF when my LO was 2 weeks old because it was really stressing me out and I gave up. I've regretted since, I feel like my body was doing exactly what it should've been and I copped out because it was too overwhelming. Well I'm 4w pp now and my breast have went back to normal but when I squeeze them I can hand express milk still, it starts off really watery and clear but then is bright white. Do you think it'd be possible for me to start BF again? I really want to give this another chance, if it is possible...should I pump just to make myself produce more?
