Can I be pregnant despite negative pregnancy tests?

Pregnancy tests performed several times with a negative result after the expected menstruation indicate the absence of pregnancy, while the credibility may also depend on whether your cycles have been regular so far. One of the possible reasons for receiving false negative tests is to perform them too quickly in relation to the day of conception. Errors in the execution of the test are also possible. If you exclude these factors, and bleeding does not come, then this should prompt you to contact a gynecologist.
