There is a rule for this, and most people have never been told it

Here is something that surprises almost everyone who hears it for the first time. The question you keep asking, did my wudu count, was I really in the prayer, did I say it properly, is not an open question in the law. It was settled long ago, and it was settled in your favour.

The rule is five words in Arabic. Al-yaqin la yazulu bi al-shakk. Certainty is not removed by doubt.

What you last knew for sure stands, until something equally sure replaces it. A doubt, however loud it is, is not equally sure. It does not have the weight to move anything.
