HELP

I updated my iphone 4s tonight, and come to find out I was forced to do a factory reset. I lost all my information which I thought was alright because I have icloud. Well it backed up my phone to April of 2013....My computer states I have not backed up to icloud since then, but my phone states icloud backed up last night? So why can I not get my phone back to what is was before?!?! Just really really really upset because I have lost all of my music I have bought on itunes and all of my photos!! Is anyone else having this problem??
