On Friday, the US Supreme Court decided to tear up "Roe against Wade", whose decision is the basis for abortion law in the United States.
The 1973 decision led to abortion up to week 24 being considered a constitutional right and against US state laws making it illegal.
Thirteen states in the United States have a so-called trigger law that now comes into force when the US Supreme Court decides to repeal "Roe against Wade".
The right to abortion is thus no longer considered a constitutional right, but each state can now choose its own abortion laws.
Prohibition of abortion directly with the decision
In the states of Kentucky and Louisiana, among others, abortion bans occurred immediately after the Supreme Court's decision as a result of their trigger laws.
In Kentucky and Louisiana, a person who wants to carry out an abortion is now at risk of up to five years and ten years, respectively, as well as a fine.
Exceptions exist if the person carrying the child risks his or her life.
However, this does not mean that every state with a trigger law automatically imposes an abortion ban immediately.
In Tennessee and Idaho, among other places, the law enters into force after 30 days from the Supreme Court's decision.
In Wyoming and Utah, the law takes effect as soon as each state's legislator approves the law.
Clinics started closing down
In a number of states without a trigger law, older laws risk coming into force.
This is the case in Democratic-ruled Wisconsin, where the state's Democratic state prosecutor is now working to ensure that the more than 100-year-old law before "Roe against Wade" - which bans abortion - does not come into force.
On Friday, abortion clinics in several of these states also announced that they were stopping all planned abortions.
In Kentucky and Arkansas, among others, the abortion clinics' decisions are linked to the new laws, while in Arizona abortion clinics decided that it was not safe to perform abortions as the law is not established before "Roe against Wade", which prohibits abortion, applies and staff can then risk imprisonment.
Wants to arrange a shelter for the right to abortion
It is far from all states that will introduce an abortion ban.
Several states have their own laws that protect the right to abortion.
Among other things, the California governor has promised to fight for the state to be aborted through a new piece of legislation that will protect clinics and people who perform abortions in California.
"In the wake of today's Supreme Court decision, which jeopardizes the health and safety of millions of women across the country, California will do everything in its power to protect the fundamental rights of all women in California and beyond," said Govin Newsom.
