I, too, had the bright red blood, very heavy. My doctor said it was not my period (even though mine was due in 3 days) and that I would probably not have another until a month later. I did, exactly a month later. I think the flow is similiar to what happens when you have the Mirena inserted, just your body getting used to the hormone or lack there of. Take care and let us know how you are doing.
