It sounds like Trichomoniasis which is a sexually transmitted infection and is spread through sexual contact with an infected partner. It's most common in women between age 16 and 35. You have to make an appt with your Dr like the above posters recommended. Make sure you ask for a pelvic exam or pap smear. It can be treated with the antibiotic metronidazole so don't worry too much...Once treated, PLEASE make sure you ALWAYS use condoms because even if you don't have anything, your partner might..Good luck!
I agree that it could be some kind of infection and you probably should go to the doctor. If you are sexually active it could be an STI. I know gonorrhea can produce greenish yellow discharge. Good luck and take care!
Hi,
Are you having any itching, irritation, or a bad odor? It could be a type of infection and I'd see a doctor just to make sure and to get the proper meds., if needed. Good luck to you :)
