should I be trying to get my ebf 7 week old on a schedule?

Right now she eats when she shows hunger cues, she sleeps whenever she falls asleep, it's different each day ... her night time feeds always fall between 2 and 4 and again between 5 and 8. But should I be trying a more rigid schedule? I mean it would work easier for me to have a normal life and not be so much of a zombie if I could get her on a schedule but again she's only 7 weeks!
