I had my last period on 10th August 23, my periods are regular with 30 days cycle lasts for 6-7days. This month i caught viral fever and was taking medicine for 4-5days (Dolo 650, Sinarest, Azee 500)between 26th August to 2nd September. and my periods was expected to come on 10th September but I am experiencing spotting (Clots of blood mucus passing) since 3rd September. It has never happened before. And it's not some mild spotting its enough so that I have to use a single pad for a day also 5-6ml of blood also comes out. I am married and using condom without miss I am not pregnant I have checked. What could be this ?
