SGI after longer sick period

If you had a job when you got pregnant (I think it's 8 months before the due date to be more exact), and you were expected to work up until the due date, you have an SGI and it won't be affected by sick leave. 

It happens all the time so it was weird that Försäkringskassan couldn't answer that. 

It also says here, that no matter what, you won't lose your SGI during the last 6 months of pregnancy:
