"who had been bleeding" or "who frequently had a flow of blood." She was probably bleeding from her womb even when it was not the normal time for it. Some cultures may have a polite way of referring to this condition. (See: [[rc://en/ta/man/translate/figs-euphemism]])
According to Jewish law, because she was bleeding she was not supposed to touch anyone. She touches his clothes so that Jesus' power would heal her and yet (she thought) he would not know that she touched him. (See: [[rc://en/ta/man/translate/figs-explicit]])
The woman was not Jesus' real daughter. Jesus was speaking to her politely. If this is confusing, it can also be translated "Young woman" or even omitted.
