What if you have had PMS symptoms for a couple of days then all the sudden they stop on morning are suppose to start your period but there is still no period?

Possible reasons for this include:

* Pregnancy: If you are pregnant, the sudden cessation of PMS symptoms may be due to the implantation of the fertilized egg in the uterine wall. This can cause a temporary drop in progesterone levels, which can lead to a decrease in PMS symptoms.

* Stress: Stress can disrupt the menstrual cycle and cause PMS symptoms to come and go. If you have been under a lot of stress, this could be the reason for your symptoms stopping.

* Illness: A sudden illness can also disrupt the menstrual cycle and cause PMS symptoms to stop. If you have been sick, this could be the reason for your symptoms disappearing.

* Changes in diet or exercise: Changes in diet or exercise can also affect the menstrual cycle and cause PMS symptoms to change. If you have made any significant changes to your diet or exercise routine, this could be the reason for your symptoms stopping.

If you are concerned about your PMS symptoms stopping suddenly, it is always a good idea to talk to your doctor. They can help you rule out any underlying medical conditions and provide you with peace of mind.
