my plan for students and teachers expired, can I access cloud?

Hello!!

I got the plan for students and teachers , which gave me 100 gigabytes of From cloud storage and yesterday it expired. I forgot to back up some of the important files and now my cloud is wiped out. 

I thought that you are supposed to have 30 extra days after expiration before they actually erase your cloud storage. 

I know it´s my bad for not backing it up in my own pc but I really thought I will get those 30 days. 

I´m mainly here to make sure that I actually didn´t miss anything or to make sure that I actually lost everything. 

Thank you for any help!!
