Must days for which one intended to fast be made up again if one then intended to make them up due to waswas (whispers/intrusive thoughts) about the validity of the fast?

We ask Allah to cure you and grant you well-being from the whisperings (waswas), for the best cure for obsessive whisperings is to disregard them. Your fast is valid, and you are not required to repeat it. The discharge of yellowish or brownish fluid after seeing the white discharge is not considered menstruation.
