Hi welcome to health care magic
First you must wait till the due date of period.. If the period is missed then you can try to do the UPT Urine pregnancy
test. the time you did is no correct.. only after 4 to 5 days of missing periods is good time.. because it ia an antibody agglutination test. requires some time to develop in the body... you must do again at around 4 to 5 days after you miss period .
