A woman who experienced nocturnal emissions but did not perform the full ritual bath due to her ignorance of the ruling: What is the ruling?

The Shaykh : This is a questioner who says: A woman used to experience nocturnal emissions, but she did not think that seeing the fluid made the full ritual bath obligatory. What is the ruling?
The answer is that if it never occurred to her that this made the full ritual bath obligatory, then she owes nothing, because she is excused by her ignorance. However, she must now perform the full ritual bath if she sees any of that.
