I have always been pretty regular with my period but last month I was a week late and this month I seem to be a month early. I don’t have a ton of blood, barely any actually. I have the brown discharge like what happens before a period starts but it’s been here for 3 days and there is more of it than usual, I need a tampon like I would with a regular period. I have never had this before... has anyone else experienced this? If it changes anything I also have an IUD.
