Late positive?

Has anyone ever still gotten negative urine tests after their missed period, but were still pregnant? I'm currently 17 DPO and I don't think I'm symptom spotting or anything like that, but I've been getting negative tests (granted they were just those little cheap dip sticks, but still). I'm just worried that I'm not pregnant and something is just wrong with me. (Also please no hate, I know the tests shouldn't be wrong but I'm young and inexperienced with the world of TTC)
