I don't think you're doing anything wrong, Miracle. The question that came to my mind is, are you using long or extra-long pads? I had the same problem as you, especially when I woke up in the morning I'd discover that I had some leakage. I was on "normal" or "regular" length pads at the time, and decided to switch to long. Since then I've had no trouble with blood going on my panties.
