Hi I'm 24 yrs old. After a miscarriage 4 yrs ago problems started I started having blood clotting in periods it's very painful when it is about to come out but once it is out i get relief until the next arrive and my periods started lasting for just one day. Pain and swelling in right lower abdomen almost every day now but year before the pain last for 1 week after periods and 1 week before starting of period it wasn't constant but now it is.
