Coffee for women?

The general verdict seems to be clear, that coffee is generally good for you. Take this huge meta-analysis for example.

But interestingly the study also warns (from the credo tldr) pregnant women and women at risk of bone fractures should be careful.

The "pregnant case" seems straightforward enough, but what about the "risk of bone fracture" case? When should we not drink coffee?

I'd be interested to delve into this!
