Hi, im fourteen years old and female. Today i leant over to grab something, i felt a trickle down my nose and mouth, looked in the mirror and realised it was blood then it started coming out of my mouth. I would say there was quite alot to say it was a nose bleed, which is why i was abit worried. A few drops of the blood was fairly thick. What could this be? Is it something i should worry about? and is there anything i should do to stop/prevent it??
