As mentioned,i had my last period on 4th march,2017.But i am confused whether it was an implantation bleeding or period because - 1st day-normal flow as usual changed pad once 2nd day-half the 1st day 3rd day-same as 2nd day 4th day-half of 2nd day 5th & 6th-spotting Moreover,had no cramp. while in the mid of my cycle i had,white stringy discharge and one day a single spot(reddish brown) and the next day once in the morning i had white and reddish brown string discharge. My periods are never regular it always go above 30days but less than 40days.
