I apologise if this has already been asked, but I have searched across the internet for quite a while and can't find a definitive answer.
If a woman starts fasting at sehri, and then starts her period during that day, I know that the fast has to then be made up after Ramadan. I also know that for the rest of the duration of her period she can't fast. But is the woman meant to break the fast on the day her period started, or does she have to continue fasting on that day even though it is not valid?
I have read many different opinions on this. I have always thought you have to continue fasting that day, but I just read somewhere that its actually haraam to do this.
