Is it obligatory to repeat prayers upon seeing a thick, circular discharge resembling seminal fluid, knowing that it may appear before or after menstruation?

It appears that the secretions mentioned are not manī (seminal fluid) necessitating ghusl (ritual bath), but rather vaginal fluids. If a woman sees manī with the characteristics described in the fatwas, then ghusl becomes obligatory for her. However, in case of doubt, ghusl is not required. When in doubt about the discharge, whether it is manī or something else, the Shafi'is hold the view that one has the choice between the two, and this opinion is more lenient. It is advised not to give in to waswas (obsessive doubts). Recalculating prayers is not necessary unless there is absolute certainty about the discharge of manī that necessitates ghusl.
