Can I Pray While Experiencing Spotting Before a Miscarriage?

In a 9-week pregnancy, the baby’s limbs and features usually have not yet formed, so the bleeding in such a case is not considered nifas (postnatal bleeding) in Hanafi fiqh. Then, if the bleeding continues continuously for at least 3 days, it will be regarded as hayd (menstruation); otherwise, it is considered istihada (irregular bleeding).

Therefore, since the question mentions only light spotting and occasional bleeding, not continuous bleeding, it falls under the ruling of istihada. You may perform Salah after making wudu, and you may also keep fasting.
