Updating that I worked through my 32 week and then went on leave. I'm 36 weeks today so I've been off for 3 weeks so that's been good.
My STD for the leave was approved after all so I get a little bit of money while on leave and then I'll get 6-8 weeks of STD after the babies come but will still take 12 weeks of maternity leave, the remainder will just be unpaid.
I went on bed rest at 33 weeks. I had STD start right away, and stayed home until the babies were 11 weeks old. My employer at the time was pretty accommodating. The reason I went back at 11 was because I would have had to start paying Cobra for my health insurance.
