It happens to me too ! She will normally wet the whole enclosure but one thing I realized are those moisture tend to stimulate the male to do more actions
As long as they are not soaking in pee or poo for 3 days or more, it should be fine. But try best to only clean after they are done locking up or both of them doesn't show any interest in each other anymore. Note that female wetting the enclosure doesn't mean confirm lock ups but that's what normally happens in breeding/
Try to check on them but minimum disturbance.
Cheers
