24hour urine collection

i was ordered by my OB to do a 24hr collection of protein and creatine. i woke up at 7am started collecting ended up going back to sleep until 11am i continued doing by collection all day and it’s not even half full and it’s 9:30pm.

It’s very dark in color as well. I’m nervous to what my dr is gonna say. I feel like i may be a tad dehydrated. Yesterday i mowed the yard some so i wonder if this is what caused it because prior to today I pee at least 30 times.
