sunesis, u're not near yr EDD yet, perhaps not counted. Like esnow mentioned, if not within 4 wks of delivery, shld not be considered maternity.
Alternatively, my colleague told me this, if possible, u try going back to work for at least a day (if within 4wks frm delivery), then they will re-count maternity from that day, if u're still on hospitalization leave. Not sure if this works at yr com. Find out more 1st... else really quite bo hua if they start counting from now.
