Question: I had my menses during Ramadaan. Actually, it has a regular pattern of six days. However, last Ramadaan it continued for only five days and I had doubts regarding its continuation to the sixth day. On the sixth day, at 6 A.M., I got up to find no bleeding but Kudrah (dusky-colored vaginal discharge during or after menstruation). I was unsure whether my period had already ended before or after dawn. Now, what should I do in this a case? Should I make up for the fast of the day I doubted? Please, be informed that I took Ghusl (ritual bath) and offered Thuhr (Noon) Prayer, and I abstained from eating and drinking since 4 A.M., that is, before seeing the Kudrah. Praise be to Allaah, I continued fasting that day and on the subsequent days without noticing any bleeding except for the Kudrah.
