I am 18, 49kg, 155cm. I had an abnormal period length in this month. I had my period somewhere around 27th November up to 12th December. After that it was clear and I ignored it. Recently, I had a slimy brown discharged and it was smelly. This morning, I had my period again. I usually wear pads, but somewhere around October, I wore tampons. Then on November when I wore pads again, I got itchings, but that problem has cleared too.
