PLEASE HELP! Lost voice memos syncing to itunes

Can anyone tell me how or if I can recover lost voice memos I urgently need? I have an iphone 6plus and was syncing to itunes. I wanted to change the music, made a new playlist and tried to add it to my phone music but it wiped out all but 3 of my voice memos! Icloud back up didn't seem to back them up and I can't find them anywhere. PLEASE HELP!!
