I once drove for half an hour to work, wearing those pads you can jump out of airplanes in, only to find my knickers, trousers, coat, car seat covered in blood. I phoned from the car park to say I'd be late and drove home to shower and change. I phoned the GP who said to call in for a prescription to stop the bleeding. Is it hormones I asked, suspiciously. Yes it is he said. You wouldn't let any other area of your body bleed like that, so don't put up with it there either. I took the 3 month course, talk about liberating not to have to take several changes of clothing everywhere for about 10 days out of every 34.
So - I would not be a fan of free bleeding, not at all.
