What the nurse was telling you is that you have VAGINITIS
, as in bacterial vaginitis (BV). It causes milky, sometimes yellow discharge in your vagina and is accompanied by a very very foul smell. Your boyfriend may have given it to you. It's an STI (sexually transmitted infection). You need to see a doctor immediately. This will not go away on its own and will make you very self conscious. The doctor will prescribe flagyl
to you or give you sporasec. That should work and you'll be cured. Please please please use a condom next time and let your boyfriend get tested and treated. He may have it and don't know it. Men are asymptomatic, meaning they show no signs. All the best.
