I am a female, 22 years old, 110 pounds (50 kg), and height 160 cm. I rarely have nosebleeds, but I had one two days back and again this morning. It woke me up before work. The last lasted for 10 minutes (it seemed like a normal nosebleed). The one this morning lasted around 45 minutes, and I have felt a trickle of blood going down my throat all day. I do feel dry (weather). I am not taking medications, except for iron pills (I have an iron deficiency).
