[Grammar] Are you having second thoughts about this?

[Ferdie11]

Hi Teachers,

I don't have a context to relate this sentence to, but can you tell me the meaning of the words second thoughts in the sentence below.

Are you having second thoughts about this?


Thanks so much.

Are you reconsidering your decision?
Are you possibly regretting the decision you made?

It's like having doubts.
