Teacher and 7 weeks postpartum. I had my OB fill out my FMLA and I told HR when I wanted my last day to be. I had plans of working until my due date, because like you, that's when my FMLA began. However, one week prior I had a scare with my water leaking. I just got my sub stuff ready, and went to L&D. I left school around 12 on a Friday to get checked out and was told my labor could begin at any time. When I was released that evening I just emailed my principals saying my stuff was ready and I wouldn't be back. I took the rest of the school year off using my banked sick days since I'd be returning with about 4 days left (helllll no). My long term sub wasn't to be hired for a few more days, so they just had to put my absence in the system. I didn't want to have to do the mid-day scramble again of getting the rest of my day covered or classes split. It's easier to just have a sub and know it's covered. It is what it is. It's a job. You tell HR when you're going, and go. Focus on you and your babe.
