It is best to use fresh urine for a pregnancy test for accurate results. However, if you need to store urine for a short period, it can be kept for up to 24 hours in a clean, sealed container in the refrigerator. Make sure to bring the urine to room temperature before using it for a test.
I´d use fresh urine as the hormones may have dwindled and the test may not be reliable now.

The storage method you use will determine how long urine will stay fresh. Samples should be stored in a refrigerator, or vacuum sealed. As long as the sample remains in its vacuum seal it may be kept at room temperature away from direct sunlight for days at a time. It will be good for up to six months, in the vacuum seal, if stored in the refrigerator.
