I thought it was implantation bleeding but now the brown blood fills up a tampon? I have a few cysts but I don't see how this could be from a cyst, and my period is supposed to start tomorrow but it's always RED!! Plus I usually go through a tampon every 2 or 3 hours and it takes a day to fill this... Could it still be implantation bleeding or just 3 days of old blood before my period? Or is this a "new" period that's not red. The pictures are in progression from 3 days ago spotting until this morning! My hubby wants me to go to the ER but I don't want to....
