Hey, I'm not a doctor but I am a nurse. The red chunks is blood and the white chunks is yeast. Are you properly inserting the nozzle in your vagina when you douche? If not, that could cause bleeding. Make a visit to your OBGYN and let him/her know about this issue so they can prescribe the proper medication. Or to cure your yeast infection yourself, buy Monistat (yeast cream), drink plenty of water, and restrict your sugar intake. If you still find yourself having an issue after a few days of at home treatment, plan a visit with your doctor.
