I finally come on yesterday morning, my period was a week late but now I'm on it isn't like my normal periods, I'm on really heavy which I normally isn't especially my 2nd day of being on, I've had some few pains in my lower left abdomen and a few clot in my blood, my blood is also really darkish red, darker than normal, I woke up this morning and it felt like someone was stretching and stabbing me in the abdomen, is all this normal or is there something wrong? All day yesterday I was in pain it didn't go away, I can't laugh or anything because it hurts:(
