am 40 years of age and have had irregular periods for last 15 years. Three years back..my periods became regular on their own. However again 6 months back i stopped getting periods. I started taking Primolut N (2tabs, 10mg, 5 days) and would normally get my period 5 days post stopping the medicine. this time, its been 8 days and no period. I have all the physical pains etc that i normally get before i start periods, but no bleeding at all. Please advice
