Regarding wet dreams in women, I recently found out that a woman who experiences an orgasm, despite having no emission of fluids, is required to do a Fard Ghusl. At the time that I found out, I recalled a time when I experienced this but failed to do ghusl thereafter (out of ignorance - I was of the opinion that ghusl is only required if fluid is emitted).

My question is: Must I make qadhaa for all the Salaah performed following this? If so, how will I determine the number if Salaah to perform as I also do not recall the exact time that a complete ghusl was performed thereafter?

Jazakumullah khair
