maternity leave ?

Ny
In exactly 30 weeks today and I work at chipotle and pretty much do every job there.. 😩😩. And if youve ever been to chipotle, you know how chaotic it gets, which means that the crew is busting their asses always. I just wanted to know when do you think is a good time to start maternity leave. Leave isn't paid and I'm not guaranteed to come back to that job because Im pretty sure that I'll find something better. Any opinions ?
