I don't think that there is any way to stop it once it starts. You need to continue it back to back with no breaks in between to end your period.
My period starts today and I want to stop it. How can I do so? However I took 2 norcolut this morning?
Don't try to stop periods, as it can cause further complications. You can try menstrual cups during your periods, so that you are comfortable during your working hours.
