I haven't claimed my maternity benefit from SSS and I also haven't filed a maternity notification then when I was pregnant. Can I still claim the benefit? My contributions are complete, by the way.

I think you can. I heard that when it comes to benefits, it's not that hard to request for it as opposed to filing for loans. I suggest you head to the nearest SSS branch or you may call them in their 24/7 hotline.
