Can I take a urine pregnancy test during the two-week wait?

You can take a urine pregnancy test, but you should still wait for the appropriate date. If you perform the urine pregnancy test in advance, the result may be a false negative. Although the pregnancy hormone is present and positive, it may not yet have a sufficient concentration to be detected, giving the pregnancy test an erroneous result.

This is why assisted reproduction clinics recommend waiting 12-15 days after the embryo transfer and usually order a blood pregnancy test, which can detect lower levels of hCG hormone than urine pregnancy tests.
