What is the ruling on breaking the fast for two days in Ramadan due to slight bleeding, assuming it was menstruation, and then it was later discovered there was a pregnancy?

Scholars have differed regarding the blood of a pregnant woman, and what is most preponderant in our view is that it is not considered menstruation. If it is established that the bleeding occurred during pregnancy, then she must make up the prayers she missed because of it, and she must make up the fasting in all cases. There is no sin upon her if she broke her fast out of ignorance, because she left an obligation due to an error and an interpretation, and she is only required to make up the prayer and the fasting.
