I usually have regular periods but this month I saw blood strains 10 days earlier and its still there is been 6 days already my actual date for periods is on 23rd but I saw strains on 16th .... usually only 1-3 days early I get my periods but every time its normal for 5days but these are only strains I am getting although I am not facing any othere health problems but yes I do have a lot of stress and 6 years ago I had an operation for removal of cysts on the outer wall of left ovary although I got a health check up recently and everything is fine now but I am still concerned. I am getting dark brown strains and I was on holiday last month and the place where I went had a very different temperature than mumbai. I am unmarried and I didn't have sex since 4 yrs I am 28yrs old.
