Hi, my period came last night but not my normal flow and 3 days too early iv been having cramps for about 4 days not and that's not normal to me either, I can always rely on my period there very much like clockwork I get cramping 1 day before hand, and is always in time, when I bleed last night it wasn't enough to even leak onto my underwear it was a wipe and when I woke this morning there was nothing, it has been on and off all day but always quite light apart from 1 gush of blood but still not enough to leak on my underwear my cramps are getting worse and the blood is getting lighter,is this something I need to worry about do u think?
