Totally agree that this is not normal. A 9 day period is longer than normal in and of itself and to then begin bleeding again and for all this time is certainly not normal. I would say it is not an injury or a miscarriage (as both would have finite bleeding time) but more like something hormonally going on that needs to be addressed. But a doctor would be able to help you. good luck
This is NOT normal. The second bleeding is not a period. It's more possible that it's an injury to the vaginal wall or possible miscarriage. Make a gyno appt asap.
