I bleed often too. Sometimes it's a moderate amount (I've never had a BAD bleed). My bleeding can be triggered by coughing, laughing, hitting waves w/the boat, sneezing, heck- probably just breathing! hahaha
I can't always figure out why I bleed, I just do. My hospital (after years, not kidding YEARS) finally listened to me that bleeding does not equal sickness for me. They would always give me IV's when I'd bleed...but that was all the time. They finally decided I was right and just let me go now!
Good luck w/it, it's so annoying at times! Like when I can't lay down flat!!
