In the name of Allah the most Gracious the most merciful
The answer to your question is as follows:
Your wudhu is not broken unless the vaginal discharge appears on the outer part of vagina. If you merely feel any discharge during namaz and you are not sure then continue your namaz and check after namaz if there is any spot. If there is nothing then you have nothing to do but if you find any spot on body or cloths then wash the smeared area and repeat the wudhu and namaz.
And Allah knows best
