Can you get a false positive?

Has anyone gotten false results in early pregnancy from a urine test? Say screening for STD/STI’s? :woman_facepalming:t4: At the very start of my pregnancy they said my urine test came back positive for chlamydia, my husband and I both took the antibiotic but I figured we had sex too early after treatment and let my doctors know at my last visit last week and they said they’d retest. I still haven’t heard back so I’m wondering if they made a mistake?

Also not wanting to hear that one or the other cheated, neither of us did and we think somehow one of us had it undetected before each other. TIA!
