I am 43 years old having regular periods. For the past 3-4 months its been changing. I had my last period on 26th dec,2011 & was expecting the next to be on jan 24,2012 or max by 26th jan,2012 as per my earlier cycles. I had gone to my family physician who subscribed deviry 10gm & i took for 1 week i.e.2 tablets per day which was completed on 10th feb,2012. I am confused whether its menopause or pregnancy.
