I say, and with Allah's success: Whoever has continuous bleeding like this is considered to have an excuse, and she performs ablution for each prayer. Her ablution is invalidated with the passing of time, and she is considered menstruating for the number of days of her previous cycle and pure for the number of days of her previous purity. If her previous cycle was five days of menstruation and twenty days of purity, her situation with the continuous bleeding is the same. She is permissible for her husband except for these five days. And Allah knows best.
