What does the presence of trace protein in a urine dipstick test indicate?

Hello doctor,

I am a 35-year-old male and my vitals as of this morning are as follows-

BP- 103/76 mmHg.

Pulse: 64 bpm.

Blood glucose: 91 mg/dl.

Weight: 220 pounds.

Height: 5 feet and 11 inches.

I have a history of health anxiety, which sometimes leads me to spiral about health concerns. I was hoping maybe you could take a look at my situation and perhaps offer some context or reassurance. Because of my health anxiety, and a family history of diabetes, I sometimes check my blood sugar or urine at home for any issues. I happened to do that today and noticed my dipstick test came up 'trace' for protein, it had bluish edges with a yellow middle then settled on a trace indicator when I checked first thing in the morning. My blood glucose was 91 mg/dl at the time. Over the past few months I have had several bloodwork or imaging studies:

Blood work - CMP with CBC (most recent attached).

Several urinalysis which all came back normal (most recent with results attached).

An MRI of the abdomen, including kidneys and adrenal glands.

EKG or echocardiogram (unrelated, due to heart palpitations).

The fact there was some trace protein in my urine has really scared me and exacerbated my anxiety. Do I have anything to worry about? Or any reason to have any additional testing? My primary care doctor says that is not necessary, but I am a little worried maybe I am missing something. After having a glass of water, and bringing my urine back to a pale yellow color, there was no protein on the dipstick. Is this fine? Any advice or reassurance would be greatly appreciated.
