Hi my name is Alex I'm 17. When I as having intercourse the condom broke and he came inside me. I'm not on any birth control, so I went and got next choice which is an emergency back up. Ever since this has happened and I took the medicine my vestibular bulbs have been swollen and hurts very bad. Also there has been white stuff coming out of me. Can you please help and explain to me what is the best thing to do and what it could be?
