What is the ruling on the bleeding of a pregnant woman? Can such women perform the acts of worship during that period?

The bleeding of a pregnant woman is not menstrual but istihadha (excuse). Istihadha blood is judged as the blood flowing from any part of the body. Ablution is nullified when this blood flows; ghusl is not required (Mawsili, al-Ihtiyar, I, 99).

If the istihadha blood comes continuously, the judgments of general excuse are applied. Accordingly, a pregnant woman who sees blood continuously performs ablution for each prayer time, and this ablution becomes valid until the next prayer time unless it is nullified by any other reason (Mawsili, al-Ikhtiyar, I, 105-106).
