My boyfriend and I have been having pregnancy symptoms for the last 2 weeks. Sleeping a lot my appetite increased his decreased. 3 days late period negative hpt. Could be pregnant?

It is possible that you could be pregnant, however, a negative home pregnancy test (HPT) result three days after your missed period does not rule out pregnancy.

Home pregnancy tests detect the presence of human chorionic gonadotropin (hCG) in the urine, this hormone produced by the placenta during pregnancy. However, HCG levels may take some time to rise to detectable levels in the urine, especially in early pregnancy.

Factors which may affect home pregnancy test results include:

- Timing: If your home pregnancy test was performed too early after your missed period, the hCG levels in your urine may have been too low to be detected.

-Dilution: Dilute urine can affect result of the pregnancy by altering hormone concentration, consider doing the test again with your first morning urine.

-Test quality: Check expiration dates on pregnancy test kits.

-Medications: Some medications can interfere with the accuracy of home pregnancy tests.

-Medical conditions: Certain medical conditions, such as kidney disease or certain types of cancer, can affect hCG levels and potentially impact pregnancy test results.

If you continue to experience pregnancy symptoms, consider retaking a home pregnancy test in few days or make an appointment with your healthcare provider for a blood test to confirm pregnancy.
