Hello
Thanks for writing to us with your health concern.
Yes, a new sexual partner could have given you the infection.
Just one day of treatment sometimes is not sufficient to cure an infection.
Also you are just assuming it is yeast infection.
It could be the beginning of a Trichomonal infection or BV (
bacterial vaginosis ) , the itching might just be the herald symptom, it might be followed by discharge , odour etc.
I would not recommend more OTC treatment.
It might worsen an infection at best and make it resistant at worst.
It is much better to have a specific infection targetted treatment.
Please see your OB GYN and have an internal exam- per vaginum and per speculum, and vaginal swab to confirm the type of infection.
Have protected sex until this passes.
Drink lots of fluids to avoid the beginning of a
urinary tract infection.
All the best.
Take care.
