A Question on Menstruation

Question : The questioner says that her cycle is every twenty days. She says that in Sha'ban her period did not come, and on the fourth day of Ramadan, some brown drops came to her after the 'Asr prayer. Fifteen days into Ramadan, blood came to her. What should she do?

Answer : Menstruation is what flows. Therefore, the drop that came to her at the beginning of Ramadan is nothing, and her fast is valid.
