When should I put in for my maternity leave?

Brittni

I’m currently 28 weeks and I work retail. I don’t work many many hours but it’s already been tough with standing all through my shifts. I was thinking maybe at 36-38 weeks I should take off somewhere in there. I’m not sure when I should though. I get an unpaid 3 months so I’d like it as close to my due date as possible but I have a gut feeling my little girl is gonna be early. When did you take off for leave?
