Is the fast valid for a pregnant woman in Ramadan after experiencing bleeding, undergoing an internal examination, receiving a stabilizing injection, and having a blood sample drawn?

Internal examination, progesterone injection for pregnancy, and blood sample analysis do not break the fast of a fasting person. As for bleeding for a pregnant woman, if it occurs at the time of her regular menstrual period and for the same number of days, then it is menstruation and breaks the fast. Otherwise, it is not considered menstruation and does not affect the fast.
