I've been having normal periods for five month's then in June it went strange.
My cycle is 31 day but for the last two months they are 21 days.
And there was no warning that it was coming, the first day I have bad cramps and mild bleeding, then the rest of the time now cramping and vary light bleeding if any at points.
My period is normally meadom in flow and have cramps most of the time and it last 5 to 6 days.
