I am still dealing with this! They have tested me for everything and it ended up being yeast. The doctor told me that it is not uncommon for a yeast infection to have greenish or yellowish discharge. Please get it checked out though! It will make you feel SO much better to know! I know how scary it is to see it at first, and I put it off for probably too long by trying to diagnose myself!
it could be bacterial vaginosis. nothing to worry about not an std, just ur body and ur partners body together causes a PH inbalance and the good bacteria in the vagina die and the bad bacteria take over. thats the smell and discoloured discharge. green discharge is also a sign of high fertility. hope this helps.
It may seem like an std but I cannot be sure. I am not a physician or a qualified medical worker but I am somebody who is willing to help. You can ask experts here if you want but you may have to pay a fee for that. They can give some insight but they would tell you to get it checked out as they cannot diagnose over the web if they cannot come up with an answer.
