You should ask Your employer about short term or long term disability. This will be deducted from your paycheck if you are allowed to enroll (usually its a specific time to enroll, its not open all year). If you are enrolled then You can get more time off paid (maybe 40% or 60% depending on what state you live in) after your maternity leave is over.
I missed the enrollment so I cant take advantage of extra time off and 40% of my pay! Im very pissed off that my HR did not do a good job of informing us. This would have been very helpful!
Oh well...
Good Luck
