Abortion has become illegal in eight states, home to more than 31 million Americans, since the Supreme Court overturned Roe v. Wade, which had guaranteed the medical procedure as a constitutional right.

Arkansas, Kentucky, Louisiana, Missouri, Oklahoma, South Dakota and Utah had trigger laws that went into effect following the ruling.

Providers have stopped performing abortions in Arizona, Wisconsin and West Virginia while legal analysis is pending. Abortions are not being performed in a total of at least 11 states.

All state abortion bans currently in effect provide an exception when the life of the mother is at risk.<

Only Utah allows exceptions for cases of rape, incest or a lethal fetal deformity.

Canadian Prime Minister Justin Trudeau said Saturday Americans can now access Canada's health care system for abortions and that will continue, according to the Associated Press.

Trudeau called the court's decision "horrific" and voiced concern that the ruling could someday allow a rollback of legal protections for gay relationships, including the right for same-sex couples to marry, according to the AP.

"Women for generations have fought for more rights in the United States, (only) to see this setback, to worry as well about how this can be expanded to more rights be taken away in the United States," he said at a press conference in Rwanda, according to the AP.

Trudeau didn't answer when asked if his government is planning to offer help for American women seeking an abortion in Canada, according to the AP.

The White House on Saturday continued to criticize the overturning of Roe v. Wade, with press secretary Karine Jean-Pierre telling reporters the Supreme Court’s ruling is “out of step” with what a majority of Americans want.

“We are going to see some nightmare scenarios, sadly, because of this decision,” Jean-Pierre said on Air Force One on the way to the G7 summit in Germany.

Jean-Pierre touted the steps announced by the administration yesterday to protect access to federally approved medication like contraception and medication abortion and to ensure women can travel across state lines for reproductive health care.

But it's ultimately up to Congress to fully restore Roe, she said.

“If that can’t happen, the American public has to use their voice," Jean-Pierre said. "In light of this decision, they have to use their voice at the ballot box."

Not on the table, she said, is court expansion: “That is something that the President does not agree with.”

Advocacy group "Not in My Marine Corps," started by former marine and Department of Defense civil servant Erin Kirk Cuomo, called on leaders to support servicewomen and families in areas where abortion bans have begun to take effect. The group has worked to raise awareness around sexual assault in the military.

The group is calling on leaders in the department and Virginia to:

"It'll be interesting to see what DoD comes out within the next several days. We've known that this is going to be happening for months now. So they should have they should have been working on these policies," Cuomo added.

Because of the Hyde Amendment, the department's military medical program doesn’t regularly perform abortions, so service members would rely on providers in the state.

Earlier this month, Sens. Kirsten Gillibrand, D-N.Y., Jeanne Shaheen, D-N.H., and Mazie Hirono, D-Hawaii, introduced legislation that did not call for a full repeal of Hyde, but for a more tailored change in policy to allow military doctors on military bases provide abortion access for service members. There is a companion bill in the House.

"While states like New York will remain a safe haven for reproductive freedom, the reproductive rights of women serving at Fort Hood in Texas or other conservative states could be in jeopardy," Gillibrand wrote, introducing the bill.
