i have this too, i htink its due to..TMI....too much stuff coming out with the blood, i still have full on bleeding and clots (large ones) i was thinking about going to the gp and having a word as it not got any lighter since giving birth, i also get really bad pains if i try wearing a tampon, i know towels are not as hygenic but it feels better letting it all flow out instead of trying to plug it and keeping most of it inside....ooohh what horrible thing to talk about...lol
