PS+ Subscription Expiration Notices?

I am just wondering if I will get warnings before my subscription expires. I am just worried it will suddenly end and I will loose the free games I downloaded.

Thanks, everyone.

You can see when it ends by pressing triangle on a downloaded PS+ game then going to information. It will give you an expires date which is your PS+ End date.

You can let the service expire and re-sub at any time to re-access free games you have "purchased"
