Is it obligatory to make up the missed prayers after it became clear that the blood that lasted for ten days was due to pregnancy and not menstruation?

Scholars have differed regarding a pregnant woman's menstruation. The preponderant opinion is that it is possible but rare. This is the view of the Malikis, Shafi'is, and Ahmad in one narration, provided that the blood has the characteristics of menstrual blood and appears at its usual time. The blood discharged by the questioner is most likely not menses, and she is not required to make up the prayers she missed due to her assumption that it was menstruation, because the Prophet (peace be upon him) did not order the woman with perpetual vaginal bleeding (mustahadah) to make up past prayers.
