I know that might sound a stupid question but EDD is 25 June. I have just been booked in for an ELCS on the 15 June due to health reasons. I had already booked that my last day of work before mat leave was going to be 11 June so i don't think that needs to change but do i need to inform work that I am now due to have baby earlier than EDD (or just say that EDD has now changed)?
