Quoting ♫ boobook ♫:" I've been super heavy for 2.5 days. Filling a regular pad every two hours and waking up every few hours ... [snip!] ... a towel. I'm wondering if this is too much? I've been through a pack of 36 pads+ some in a new pack, since Christmas morning."
Is this your first or second postpartum period? If so, I would say that's pretty normal. My first 3 postpartum periods were HORRIBLE. Really heavy and seemed to last forever (usually I have medium-to-light periods that last 3 days max.) By about the fourth one, however, they started to go back to normal.
If it's NOT a postpartum period, however, I would probably call your doctor. You may need to be put on iron supplements, if nothing else, because all that blood loss can cause anemia. They may also check you for fibroids, which can cause heavy bleeding.
