Had better + Tag question

[Serzige]

Hi there!
I wonder what would it be the correct tag question for this sentence,

"it is about to rain so we'd better take an umbrella, don't we?"

or

"it is about to rain so we'd better take an umbrella, hadn't we?"

Thanks

The 'we'd' is the abbreviated form of 'we had' - so the correct tag would be 'hadn't we'.

We'd better take an umbrella, hadn't we?
