I had an ultrasound at 6 weeks 3 days and there was a sac but no heartbeat. The urine test at visit was positive, but doctor changed it to negative after the ultrasound. Since then symptoms have stopped. Having off and on cramps and moderate hip and back pain. Also feel very hot and have moderate headache. I just want a direct answer as the weeks of uncertainty is driving me crazy. And I find it odd the doctor changed the urine test result based on the ultrasound.
