Have you??

have you ladies ever had a period so light is just spotting? I normally have a period where the first day is spotting mostly old blood, as the day goes on it will start to turn bright red. But this time it's all been old blood with very little new blood. There isn't enough to fill a light tampon. I'm on my third day and should be bleeding enough to have to change my tampon ever 4 hours give or take. I also figured that since I missed my period last month that I would definitely bleed normal this month since I'm used to missing then bleeding old for a day then new... I do have pcos so I tend to miss periods a lot but I've never had bleeding like this before.
