This morning when I removed the cup it was empty (very unusual for day 3 but I was not terribly concerned). I washed it and reinserted.About an 60 to 90 minutes later, I removed it before getting into the shower and it was full. It seemed like what would have normally come out over night can out all at once. Since then I have checked it several times because I was worried about leaks but there has been a 'normal' amount of flow in it each time.
I have never had anything like this happen before. Is it possible that the Diva somehow blocked the flow all night and then when repositioned this morning it all came out?
