welcome to HCM,
your symptoms of itching , thick white discharge, lower stomach pain , suggests that you are suffering from vaginal infection
. it could be a fungal infection
since the description given by you of the discharge is a thick white, which generally occurs in fungal infection.
it could be an allergy
as well since you have itching and burning sensation. you did not mention if you have got any rashes, or may be the white discharge may be covering any rashes present.
at present what i can suggest you is maintain personal hygiene, keep your private parts dry as far as possible, maintain abstinence till the infection subsides.
you can use cansoft
cl or candid/ flucan vaginal cream if it is available over the counter at your place.
thank you for consulting,
take care and get well soon
