Does reddish-brown discharge for a pregnant woman in her first month necessitate invalidating her fasting and prayers, or making them up?

Scholars differed concerning the blood of a pregnant woman, but the preponderant opinion is that it is not menstruation. Therefore, a pregnant woman must continue to fast and pray. The questioner's fast is valid, and her cessation from prayer due to ignorance that the blood was dysfunctional blood carries no sin. She must make up the prayers she missed, which she has already done.
