Already being late with your period due to excessive exercising... will the come back on couple of days you suddenly stop exercising?

Stopping exercise will not instantly bring back your period. The hormonal changes that cause irregular or delayed periods due to excessive exercise can take time to return to normal. It may take a few weeks or even a few months for your period to resume its regular pattern after you stop exercising excessively.

If you are concerned about the absence of your period, it is always a good idea to consult with a healthcare professional. They can assess your individual situation and rule out any other potential causes of your missed period.
