Usually not. If you do use conjectures, you should make it quite clear that the proof stands and falls with the truth of the conjecture. That is, if the conjecture happens to be false, then the proof of your statement turns out to be invalid.
By creating a strong inference, you can then put your ideas to the test. After close observation, you can then rule-out any incorrect guesses.
Counterexamples are used to test the validity of conjectures by providing a specific instance where a conjecture fails. If a counterexample is found, it refutes the conjecture, demonstrating that it is invalid. Conversely, if no counterexamples can be found despite thorough testing, it supports the conjecture's validity, although this does not prove it universally true. Thus, while counterexamples are critical for refutation, their absence strengthens the case for a conjecture, though further proof may still be needed for confirmation.

The word invalid is an adjective. It describes something that is not valid.

The premises on which he based his conclusions were invalid.

Like telling someone.. "Is an invalid sentence." would be incorrect. "That is an invalid sentence." would be correct.
An invalid argument is when the facts you are using are invalid or your forms of defense are wrong or incorrect, a valid argument is the opposite of an invalid argument. "There is a windmill in my beard. your argument is invalid." (This is a good example of a bad contradiction)
