After Hermione's second miscarriage, Draco had thought to tell her they would stop. That it wasn't meant to happen. But he had never found the heart to tell her. She wanted children and he would be damned if he couldn't give her at least one child. He had even been prepared to ask for medical help, magical or muggle. He had never told Hermione this, because that was when they discovered she was pregnant for the third time.
