A little bit of mold on bread will not hurt you.
If you happened to eat a bit of mold or even an entire piece of bread that had mold on it then it's unlikely to hurt you.
The moldy bread might give you a stomach ache, make your vomit etc but the moldy bread is unlikely to actually make you deathly sick.
You might feel bad for a day or so after eating the moldy bread but you'll be okay.
The mold on bread tastes awful and you'll usually not want to eat the rest of the moldy bread anyway but if you did happen to eat moldy bread then a piece of moldy bread will not hurt you.
I would not recommend eating an entire loaf or more than a few pieces of moldy bread though because it can make you sick to the stomach and could also make you really sick.
But just eating a little bit of mold on bread is not gonna harm you.
You can remove the moldy parts of the bread and eat the rest though.
