hello and welcome,
It seems that you have an infection. They may occur despite a monogamous relationship as other routes than sexual can cause these infections. Use of tampons, not changing the liner twice daily or even the undergarments can harbour the bacteria. Also sometimes conditions like diabetes
predispose to infection. Trauma caused by friction during sex also causes such infections.
It is best to get a vaginal swab tested to determine the offending organism after evaluation by a doctor.
Drugs like mixed vaginal tablets
containing a antifungal, antibacterial and antiparasitic
drug are very helpful in providing relief.
if you cannot get a prescription soon you may use monistat as the description of the discharge indicates a fungal infection
Other measures include avoiding sex till it heals, keep the area clan and dry, clean undergarments daily with hot water and use vaginal pads instead of tampons.
Hope this satisfies your query.
Thanks for using HCM.
Feel free to ask any more questions that you may have.
