Hello Maam,
There are few reasons why periods aren’t coming and pregnancy being the first one which you have already ruled out . So to get to know the other reason an USG of lower abdomen / TVS Pelvis should be performed to check in meanwhile whether you have PCOS or not .
But since you are not
pregnant , you can commence your period by having
Tab. Deviry : 1Tab twice daily after meal for 5day
and after that your periods will start within 2-3 days of completing the medication .
Dont worry maam and get yourself check as well why is it happening .
