Thank you for your question. It is an honor to be of some assistance to you.
Your daughter most likely has bacterial vaginosis
that is leading to the discharge - it does not usually cause pain however. She may need oral antibiotic therapy - metronidazole for at least 2 weeks to restore the normal flora of the vagina
The cramps can have several causes: dysmenorrhea
(born to have bad cramps), and endometriosis
are the most common causes at her age - and the best treatment for both is birth control
pills. They dramatically decrease menstrual cramping
and work wonders in regulating periods.
Please have her check a home pregnancy test
- just in case!
She has had all of the necessary testing done it seems, but if you are unhappy with her care - she should seek a second opinion as soon as possible.
I hope you find this information helpful.
Please, do not hesitate to ask me any questions in the future or to request me.
