An employee looks over a patient's file at the Hope Medical Group for Women in Shreveport, Louisiana, April 19, 2022. - On September 1, 2021, one of the most restrictive anti-abortion laws in the country went into effect in the Republican state of Texas, prohibiting all voluntary termination of pregnancy (abortion) from the time a fetal heartbeat is visible on ultrasound, about four weeks after fertilization. With a population of 30 million, Texas is the second most populous state in the country and this law has driven patients to the rapidly overflowing clinics of other states, forcing them to inexorably delay their abortion due to lack of space.
