restore notes vs new computer backup-not

how do I restore notes; new computer shows iPhone(2) after sync it doubled my notes in phone when I went to delete a duplicate my phone wiped out all my notes? checked icloud and it does not have a backup of my notes even though my settings show on? my email accounts only backed up one single note back in april? under preferences there is only one back up without my notes-how do I get my notes back?
