I just noticed that my cum is brown i'm a female and this has never happened before can you help with this i do get the needle so i don't have my peri?

Infection? Bleeding?: I'm guessing that "cum" means vaginal discharge. Colored vaginal discharge is abnormal. Dark brown can be due to bleeding, but lighter brown (tan), yellow, etc often is caused by an infection. Depending on your age and sexual lifestyle, STDs might be possible. See your doctor, preferably the doctor or clinic where you get your contraceptive shots. Good luck!
