Are we attempting to rule out the possibility of miscarriage? How many hours are we deciding is "one day"?
If we are saying 8 hours for a day, I would deem 5 pads to be normal, that's a change almost every 2 hours.
How much difference would there be in your definition of a "full" pad to hers?
I would think a typical pad could handle 20cc of fluid. But there are so many variables when questioning flow rate.
So, she hasn't had a period in 2 months. Is it normal for her to be irregular? Is her flow tyically light and now this 5 pads is a lot for her?
Are you really only curious how much it can hold, or are we going somewhere with this?
