Hiya, I am on my period, day two now, and yesterday day One, I was in extreme pain where I couldn t stand up straight and felt light headed and faint, today I am still in more pain than normal and I have grey coloured lumps / clots coming out of my vagina but the biggest I have seen, perhaps a inch thick and a inch long blobs? Why is this please? Why is it so painful thank you xx also my period is a week late x
