Hi, Usually the genital area especially around clitoris will have rich blood supply, so minimal injury there can lead to bleeding. According to your description there could be small injury due to scratching and might have led to bleeding, usually this type of injuries will heal by themselves. But as you are mentioning that you are having discharge, better to consult your gynecologist once and get examined to rule out any possibility of infection. By clinical examination the exact cause can be identified and treatment can be taken. Meanwhile you can take sitz bath with luke warm water and with little disinfectant like dettol liquid, which can help in reliving the pain. In case of mild infection, analgesic with anti-inflammatory drugs and local antibiotic can cure the problem. Hope I have answered your question. Let me know if I can assist you further.
