Your pee will be so diluted at this time of the day that at this early stage of pregnancy it defo wouldn't show up on a test. Best to use first morning urine, as its concentrated from not drinking fluids over night and therefore the HCG hormone that indicates pregnancy is more present.
Honestly, I know how tough it is, but no amount of worrying will change the outcome of this pregnancy.
Statistically you're very likely to have a successful pregnancy so try to stay occupied and trust that your body's got this covered.
