Hi,last period:2/08/2014 now is 21/09/2014 im not period still beta hcg result was:flag result 3,reference range:positive:more than10 am i pregnant?

Depends on sex day: Result says not prenant. A urine preg. test gives a reliable result 3 weeks after sex (3 weeks after when conception might have happened) 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. If a woman has her normal regular period, then she is not pregnant, and a test is not needed
