Period is 12 days late from due date, it has been 6 weeks since the first day of last period. Menstrual cycle has been very regular before this. Primolut N has been suggested to get period but I am unsure about taking it since I have heard its possible for women to miss some periods due to stress or other factors and that doctor should be consulted if you miss period for 3 months. So is it too early to take the medicine, if yes, how long should I wait for any course of action
