False-Positive test?

Patient: Hi,I did two tests at the doctor’s, one to test my urine sample and the other was a pregnancy test.the doctor was about to throw the pregnancy test away but then stopped and waited for about 3mins before saying that the result says I may be pregnant.He wasnt 100% sure himselfIn such scenario, is it best to redo the test?I dont want to be pregnant at this stage in my life so I am immensely nervous

Symptoms: I have no bloating, no morning sickness, no nausea, I sleep normally and I dont feel tired nor exhausted
