Hello dear user of HCM! Welcome and thank you for sharing your concerns with us! I understand your concerns you are describing in your query. Yellow discharge in most of the cases comes as e result of a STD. It may be caused by gonorrhea, chlamydia, tichomoniasis, or other vaginosis. Except the discharge other symptoms may be found like, bad smell, itching, frequent urination etc. To find out what is the specific infection you have to contact your doctor and do the secretions test. After you get the results you will take a cure of antibiotics for the gonorrhea or chlamydia, and antiparasitic drugs for trichomoniasis. The same cure must be taken by the partner If you are sexually active with your partner. Try to avoid sexual intercourse or have protected sex while on medication. Take care, and all the best!
