I am 14 days late on my period even though I am usually regular (I track my periods with the Flo app).

There are many factors that can cause a delay in menstrual periods, such as illness, stress, fatigue, changes in routine, or even for no apparent reason. It is also common for the characteristics of menstrual flow to vary over time. In the absence of other symptoms and with a negative pregnancy test, it is recommended to monitor the situation. If the delay persists next month, it is advisable to consult a healthcare professional as a precaution.
