I missed my period, did a urine test it said positive but then blood test did not pick it up?

Tests are accurate: For such instances, a person can recheck urine after a week. Maybe one was temporarily pregnant. A urine test gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test.

Trust blood test: The blood test is very accurate. Would trust the blood test results.
