I don't know if what i'm having is my actual menstrual cycle. I use a period calculator and it said i should be getting my cycle on jan. 30 but it started jan.24 and it is not flowing normally like any of my cycle. i have light bleeding where it wouldn't fill my pad for the whole day but alot of clotting when i sit on the toilet. This has never happen to me before. so is this still my period are not?
