I am unmarried. I have irregular periods. I got my last proper period on 25 October 2014. After that two months I did not get my periods.from January I could find few drops of blood stain at an interval of every one or two days . I do not bleed properly . I consulted a doctor for my irregular periods,she gave me a medicine and then I had my periods.but this was in October 2014 ,after that I didn't get my periods. Please help .I am working .Is this regular spotting a sign of any kind of disease?I don't have any pain or cramps during this..
