Hello and welcome to HCM
The white spots, swollen labia
and itching that you are experiencing can be due to allergy to the new pads.
Discontinue its use and try some other brand.
Burning sensation white urinating can also be due to urinary tract infection
Get a routine urine examination. In case there is infection of the urinary tract, there will be characteristic findings.
Since, there is no vaginal discharge fungal infection
If you get vaginal discharge in future, get the vaginal discharge examined.
Thanks and take care
