You are early in pregnancy - HCG ,( the hormone tests pick up) vary through the day in urine as concentration of urine changes. I'd suggest booking into the doctor's in about 2 days time and try not to drink too much before the appointment or take a morning sample with you as levels double every couple of days so should be picked up by then
