Can you be pregnant and hcg level not show up?

Yes, it is possible to be pregnant and have hCG levels that do not show up on a pregnancy test, especially if the test is taken too early. Human chorionic gonadotropin (hCG) needs time to build up in the body after conception, and very early in pregnancy, levels may be too low to detect. Additionally, some women may have irregularities in hCG production, which can also affect test results. If pregnancy is suspected despite a negative test, it's advisable to consult a healthcare provider for further evaluation.
