One of the nation’s strictest abortion laws will take effect in Iowa on Monday. Abortion care providers in Minnesota expect an increase in patients as another border state limits abortion access.

The Iowa law prohibits most abortions after six weeks of pregnancy, when fetal cardiac activity can be detected but before many know they are pregnant. The only exceptions to the ban are in cases of rape, incest or to save the life of the patient.

Previously, Iowa had permitted abortions until 22 weeks of pregnancy.
