Hi, I am 33 years old female, my problem is I had my period on 3rd of october 2016 which last for 6 days and again on 23rd of october I again had my period and flow is also very heavy. I am suffering from dengue since 17th and my wbc are quite normal and platelets count are 86000. Can I know why my periods are in 10 days, earlier in last month they had to start on 26th of september but they where late 1 week and started on 3rd of october. What is the reason y they are so early in this month. I have not had sex also, is it a cause of dengue. Kindly help me.
