24 hour urine test

Dee • First pregnancy was an ectopic. Second I miscarried at 12 weeks. 3rd I miscarried at 5 weeks. Hoping 4th works!!!
Anyone else have to do a 24 urine test? What was the reason and what were your results? My doctor has me doing one as my swelling is so bad but no elevated blood pressure or protein in my office urine samples.
