My last period was July 9-12. Today is August 9th and my next scheduled perioodd is this month from the 11-14. For exactly a week today I've been experiencing a runny discharge, its brownish pink with a foul odor. I've had no cramping etc. Im not on birth control but I track my ovulation and menstrual cycles. My period are very sporatic and vary greaatly in flow and color. I'm worried tthat I may have cervical cancer :( pregnancy is not really a worry for me, I have no symptoms whatsoever. Could this be infection? Its not enough to wear a tampon but enough to bother me when its on my underwear, help me please!!
