Jelly like discharge thats clear with white, lower left back pain with dull ache and migraine.have a doctors apt 2 weeks from now but would like advice?

Go to an urgent care: Perhaps you can call your doctor's office back and let them know that you have an acute problem that really cannot wait two weeks. Some offices do offer same-day appointments but you have to let them know that there is a problem. I don't think your doctor would want you to remain in pain, with a migraine, and with an unknown discharge for that long without taking a look at you.If not, urgent care.
