Blood in urine dip

So I noticed some white particles in my urine yesterday and went today for a urine dip. They tested for leukocytes, protein, glucose, ph, blood, and a couple other things looking for infection.

All was normal, except it was positive for blood, but no infection . No symptoms, no pain, no burning, no urgency - just a positive dipstick for blood.

I’m 22 weeks 4 days pregnant and worried since I can’t call my doc until tomorrow.

Also read dipsticks have a high false positive rate for blood and hoping that’s it 😩
