Clinic urine test

Hey guys... So I have taken a few pregnancy tests and they have all been negative. The only thing that worries me is that I took them before my missed period. So there’s always a chance they could be false negatives. I went to the health department and they did a urine test as protocol when I went to get birth control. This was a week before my period was due. I still Haven’t started my period but I haven’t taken a test since my period was due. I plan to take one today but my question is has anyone done a urine test at a clinic and gotten a false negative?
