You should definately mention this to your care provider.

From the information you've described it sounds very much like either Galls Stones or Kidney Stones like others have said.

I've cared for a Woman on the Antenatal Ward who had Gall Stones and she was in a huge amount of pain and the pain was coming in waves like labour contractions. She would also vomit when the pain was there.

If you don't feel "listened to" by your current care provider, I would be finding another Dr very soon.

Good luck!
