I've never heard of this kind of discharge causing periods to cease. Is there any possibility that you are pregnant?
You discharge sounds like a symptom of bacterial vaginosis which can be easily treated.

refer back to "White discharge delay my period ?" Im not pregnant. may i know how to treat the bacterial vaginosis?

In some women, it goes away on its own. Most often, it is cured by prescription antibiotics.

thanks for the information.
