Synced another device to mine, lost everything!! HELP?!

I plugged my Iphone 5 into my computer for the first time. My husband had already synced his, however, I didn't realize that it had named his device with my name. I selected my name to sync my device and it synced all of his stuff to mine. Thus, deleting all of my stuff. I hadn't made an icloud account yet, I was able to restore my apps through my itunes account (which i could care less), but is there a way to get all of my pictures back??!! HELP!!
