Hello my name is***** look forward to assisting and am very sorry to hear that you are having this problem.
Have you used the card since then? When deleted if you use the card the new items over write the old ones.
You may be able to get some back but it is possible they were over written.
Download and install recuva from here: Click HereChoose priform under the free version.Make sure the camera is connected to the computer and open recuva.Click next and then choose pictures and click next again.Choose on media card or ipod then click next.Put a check in the box that says enable deep scan and then click on start.If anything at all can be recovered this will find it.If it does not find anything unfortunately although I wish you could you will not be able to recover anything.If you have any questions at all click on reply to expert and let me know.If not please don’t forget to leave a positive rating for my help - it is greatly appreciated.
