when to start maternity leave?

S

so I'm a teacher and due May 30th. I was trying to make it to may 24th but I'm just tired. I would like to start my leave tomorrow. I'm 38.4, 4cm, 90% effaced, baby is engaged. I have a 3 year old. I drive an hour. I do have a sub assigned for me and already showed her the ropes. the problem is at this point, I would have 5 days unpaid. I did submit paperwork for sick bank leave but it's up to the superintendent to decide if I'm eligible/get it. what would you do? thanks for any and all advice.
