Daily miniature periods.. Ground hog day

So I'm about 3/4 weeks late. I've had negative pregnancy test. I started taking some supplements, trying to get my period to start. For probably 4 days I've woken up in the morning with moderate bright red bleeding, that gets lesser through the day and by 4 or 5 the afternoon I've completely stopped. All to do it again the next. I have no cramping or any of my usual period symptoms.. Any ideas? It's like menstrual ground hog day.
