"I am 5 days late on my period, which is usually very regular."

It is possible that a delay in your menstrual cycle could be a sign of pregnancy. In such cases, it is recommended to take a pregnancy test, such as one from the brand Première Réponse, which may provide earlier results. If the test is negative, it is advised to wait a few more days and retest. Ultimately, if you continue to experience a delay in your cycle without a positive pregnancy test, it may be beneficial to consult with a healthcare professional for further evaluation.
