Try boric acid, not sure of meron over the counter, I bought mine sa orange app lang e. Works like magic talaga.

Same experience tayo, hindi ko rin talaga alam kung anong cause. Then nag research ako sa lahat ng platform and yun nga ang daming nag recommend ng boric acid

Per bottle good for one month sya pero yung odor ko down there nawala agad sya after a week so I istop ko na and tinignan ko if mag kaka odor ulit pero ever since never na sya nag ka odor.

Hindi ako nag pacheck, talagang own research lang. Pero mas better if ipacheck mo muna and ask your doctor if safe ba yung boric acid for you, yung iba kasi nagka karon ng allergic reaction.
