Okay this is really frustrating. I have tried multiple brands of tampons and this always happens. I put it in, and a few hours later I go to the bathroom and there is a huge amount of blood on my underwear so I grumble about forgetting to change tampons. I pull out the used tampon and its not even full! Usually its less than half covered with blood! How am I leaking on my underwear and not filling up the tampon? O_O (yes, I even tried tampax pearl because they expand width-wise, and I'm not using anything bigger than "regular" absorbancy because the bigger ones are painful.)
I don't know if it is relevant but I am 22.
