unpleasant smell

mariam

last month my period for four days was late taught I was pregnant until I saw my menses which flows well but has an irritating odur which was unsual

today glow information gave me 28 as my day for my period but saw it today and still has the same smell which have not experienced before ....what could have been the cause of the smell and the blood clot as if I have miscarriage which am not sure ...
