Neg pregnancy and prolactin urine tests, but still pregnant?

Pregnancy test. If there is reason to believe you may be pregnant, a repeat urine test or getting a blood pregnancy test may be needed. If all of these are negative, it is unlikely that you are pregnant. See your doctor for more assistance.
Not likely. Pregnancy tests test for the hormone hcg. If your urine contains no detectable levels of hcg, you are highly unlikely to be pregnant. A prolactin test is not relevant to pregnancy. If you are concerned and have only used home pregnancy tests, talk to your doctor about blood or urine tests through a medical laboratory.
