I am 16 years old i am a female and my period recently ended it ended september 12 and i masturbated 2 days after it ended and i spotted brownish vaginal discharge after so i thought it was just residuals but this september 15 i masturbated again really hard using a dildo and i noticed brownish vaginal discharge after two days i am worried it might me cervical cancer even though my periods are regular, it didnt last longer his last time nor was heavier, i dont have back pain or any other thing but my vaginal discharge that has became brownish i got to mention it does not have a foolish smell but i have noticed my vagina is dry. should i worry about possible cervical cancer or could it be just because i masturbated an my period or an unbalance of my hormones? if it could be an unbalance of my hormones i would like to know if this is something to worry about and how can i treat it
