As someone who suffered with awful recurring UTIs (until I figured out what was causing them and how to prevent them) I will echo the advice of those who have posted before me. All the over-the-counter "remedies"/home remedies/cranberry juice in the world can NOT help you once you have a bladder infection or UTI. All they can do is mask the symptoms. If you wait 3 or more days without seeking treatment you can and will become VERY ill.
The infection can damage your bladder or urinary tract and/or can spread to your kidneys and cause permanent damage. UTIs are some of the nastiest thing in the whole world, I am suffering from a distance along with you - I feel your pain.
Please go to a walk-in clinic in a neighboring town or to the ER and do what you need to do to get the help you need.
