I do not know if any one knows anything about it. I had mine put in October of 2007. I had one period right away then they stopped. And thats what my OBGYN told me should happen and its normal. Then this morning i woke up and did the normal pee thing and i am bleeding like dark red. And its not a lot like a period it is light and i have no cramps. I called to talk to my OBGYN but shes on baby delivery today. I do not know if i should just go to the hospital or just assume i am having a period.
