I accidentally restored my iPhone 5c?

I got my phone in November of last year. From my old phone to my new phone then, I used my dad's laptop to backup the pictures I had on my old phone to my new iPhone. Today, I was hoping to delete some of those old photos, and without thinking I ended up restoring my phone. I have never backed up my iPhone (which I now know was completely stupid). I lost precious pictures and contacts. Is there anyway possible I can get these pictures back?
(a simple "no" is okay)

The itunes backup contains camera roll photos. If you have an itunes backup then restore from that. If it dose not work i sorry that The only photos that you can delete directly from the phone are ones in the Camera Roll. If you deleted other photos, that had to have been done via the sync process, and you can just sync them back.
If it is photos in the Camera Roll, then if you have a backup of the phone while the photos are on there, you can restore to that backup, but understand that takes your phone back to that date and time and anything done since that date/time will be deleted.
