Hi, Welcome to Healthcare magic. I am Dr Ramadevi Wani. I will be answering your concerns. Normal vaginal discharge does not have odor. It is clear from your notes that you have infection. You most probably have Bacterial vaginosis. Bacterial vaginosis is caused by imbalance in the amount of bacteria in the vagina. This infection usually causes grayish discharge with strong odor particularly after intercourse. Sometimes it can be orange. It is not associated with itching or burning. Trichomoniasis a sexually transmitted disease that can cause orange coloured discharge with foul smell. It is associated with itching, soreness and pain while passing urine. Since you say that you were tested for STDs and were negative for them, in all probability you have bacterial vaginosis Please consult another doctor for internal examination. The doctor may treat you based on clinical examination or may take a vaginal swab for testing the organism. You need to get your Pap smear done if it is due. I hope this is helpful. If you have further concerns, I will be happy to answer. Best wishes, Dr Rama
