Stage of what?: I'm not sure what you mean.... at what stage of pregnancy? Or what stage of expiration date of the test? A urine pregnancy test will be positive all the way through a pregnancy and sometimes up to 3-4 weeks after delivery. As for expiration date, I would trust a test the most prior to it's expiration date, but it's likely it's still accurate for 6 months after.
