After my period i had this foul odor smell. After 3 days of my last period i had green clumpy mucus and it smells so bad. The next day with that o had bright yellow mucus and stink. I dont know what it is. I tried to put garlic inside me and soak my private part on apple cider vinegar with warm water. And yesterday my mucus is color brown and still stink.
