The U.S. Food and Drug Administration on Thursday approved the first over-the-counter contraceptive pill, paving the way for millions of women in the country to purchase birth control without prescription.

The approval comes as more states ban abortion following a ruling by the Supreme Court last year that overturned the Roe v. Wade decision to legalize the procedure nationwide.

A group of abortion providers on Monday filed a lawsuit aiming to preserve access to the abortion pill mifepristone as anti-abortion opponents aim to ban it in a separate case.
