Eight years have passed but Amparo Andújar Maldonado does not forget. She lost her first child while she was approaching the fifth month of her pregnancy. Nor does she erases from her mind giving birth to a disfigured fetus, with cranial malformation, something incomprehensible for a healthy 27 year old woman, counting with quality prenatal care.
