Urine Pregnancy Test

So I was supposed to start my period the 27-30 of September but I never did. I'm a week late and all negative tests. Today I went to the doctor just for regular annual check up and Pap Smear they did a urine test also to see if I was pregnant but it was negative. The appointment and test were done around 2pm. Should I keep retesting?! What would y'all do?!
