What is the ruling concerning the days when I swallowed blood from my gums while fasting, given that it was difficult to expel, and I do not remember the number of days or if I swallowed it intentionally?

Swallowing blood intentionally that comes out from the gums is considered a fast-breaker and necessitates making up the fast. Moreover, it is impure, and it is forbidden to swallow it in any case. It must be spat out immediately, even if using tissues. As for the days on which blood was swallowed intentionally, they must be made up after ascertaining their number until one is reasonably certain of having fulfilled the obligation, which is the more cautious approach, while some are of the opinion that making up the fast is not obligatory if there is doubt about it. However, swallowing it unintentionally does not invalidate the fast. It is recommended to seek treatment for bleeding gums.
