What it means
うか〜まいか expresses uncertainty or deliberation about whether to do something or not. The first verb uses the volitional form followed by か, while the repeated dictionary-form verb is followed by まいか. It is commonly used with verbs such as 迷う, 悩む, and 決める, and has a somewhat formal or literary tone. The main clause can still be made polite without changing the construction itself.
Usage note
The negative-volitional ending まい is attached to the dictionary form of the repeated verb. This pattern is mainly used for deliberate decisions and is less natural for simple factual questions about whether an event will occur.
