Should a wife make up her prayers if her pregnancy is confirmed and she stopped praying due to spotting after her menstrual period was due, and is she obligated to pray now?

If a woman experiences her menstrual period as spotting, this spotting is considered menstruation under two conditions: that its occurrence is fifteen days or more after her last period of purity, and that its flow continues for a day and a night or more. If these conditions are met, then the woman was correct in not performing the prayer, and there is no make-up prayer due upon her, even if her pregnancy is discovered later.
