Thanks for posting your query at DoctorSpring.com
I can understand your concern.
From your description it seems to be a yeast infection. It's normal for a lady in sexually reproductive age group to have yeast infection at times. It can be easily treated.
I would recommend that you take an anti fungal tablet called fluconazole 150 mg once a week for two weeks. Application of canestan cream twice a day for two weeks will be helpful.
This will help resolve your concern.
Please let me know if you have any queries.
