Does a woman have to get a paternity test while she is pregnant or can it wait till the baby is born?

A woman does not have to get a paternity test while she is pregnant; it can wait until after the baby is born. However, there are non-invasive prenatal paternity tests available during pregnancy that can determine paternity with a blood sample from the mother and a cheek swab from the potential father. These tests are optional and not required, as traditional paternity tests can be performed after the child is born. Ultimately, the decision depends on the individuals involved and their specific circumstances.
