It may be that you have a UTI, bladder/kidney infection. I would call and see your doctor just to confirm or rule this out. In the mean time, drink lots of water and do take it easy. You don't mention anything about bleeding and/or spotting. So at this point I wouldn't think any type of miscarriage. If the cramping and back pain is severe, you may even want to be seen yet today.
