GS3 won't recognize my sd card...help!!!

My Galaxy S3 will not recognize the original microSD card that came with the phone. I took it out, cleaned it and the surrounding phone, but no luck. I then bought an adapter and when I insert the microSD card into the adapter and put it in the SD card slot on my laptop, the laptop doesn't even recognize the card. I tried with another SanDisk microSD card and it worked, but neither my phone nor my computer will recognize it. I've tried everything. I really need the documents and photos I've saved on my phone.

HELP HELP HELP! I'M SO FRUSTRATED
