(CNN) -- The near-total ban on abortions signed into law in Alabama on Wednesday, May 15 is just one recent development in a country-wide, state-level fight over abortion.
A couple states have passed legislation attempting to solidify abortion protections, but the majority of states in the fight are working to restrict abortions.
Restrictive laws may be unenforceable because of the Supreme Court's Roe v. Wade decision that legalized abortion in all 50 states, but abortion opponents are hoping that the legal challenges will serve as a vehicle for the Supreme Court to eventually overturn the Roe ruling.
Here's a look at which states have joined in this legal effort over the past year:
States that already passed anti-abortion bills
Alabama legislators passed a bill banning abortions with very limited exceptions: "to avoid a serious health risk to the unborn child's mother," if the "unborn child has a lethal anomaly" and if the woman has an ectopic pregnancy.
An amendment to exempt rape and incest victims failed to pass. The law calls for doctors who perform abortions to be treated as felons and face up to 99 years in prison.
Mississippi Gov. Phil Bryant signed a "heartbeat" bill in March. Exceptions are to prevent a woman's death or her serious risk of impairment.
"The heartbeat has been the universal hallmark of life since man's very beginning," Bryant said in an address before signing the bill.
Ohio Gov. Mike DeWine signed into a heartbeat bill in April, a day after the state House and Senate passed the law. Similar legislation was vetoed by former Gov. John Kasich before he left office.
Georgia Gov. Brian Kemp signed a bill last week that would ban abortions if a fetal heartbeat can be detected. The American Civil Liberties Union has said it will challenge the law in court.
Current Georgia law allows women to undergo abortion procedures up to their 20th week of pregnancy. The new law would generally ban abortions after a fetal heartbeat is detected and takes effect on January 1, 2020.
Kentucky passed a "heartbeat" bill in March, but a federal judge stopped it from being enforced.
Arkansas Gov. Asa Hutchinson signed a bill in March that bans abortions after 18 weeks into a pregnancy -- six weeks before the standard set by Roe v. Wade -- except in medical emergencies and in cases of rape or incest.
Utah similarly passed a law that bans abortion after 18 weeks gestation, but the law was blocked by a federal judge in April, CNN affiliate KSL reported. The state and defendants agreed to the injunction and Salt Lake County District Attorney Sim Gill, a defendant in the case, said he won't enforce the law, KSL reported.
In Iowa, Republican Gov. Kim Reynolds signed "heartbeat" legislation in May 2018, but a state judge struck down the law this January.
The judge wrote in his decision that defenders didn't identify a compelling reason for the ban. Reynolds said she was disappointed by the decision but decided not to appeal the judge's decision because she saw "no path to successfully appeal the district court's decision or to get this lawsuit before the US Supreme Court."
States working to pass anti-abortion bills
The Missouri House and Senate have approved a bill that prohibits abortions after eight weeks of pregnancy, sending it to the desk of Republican Gov. Mike Parson, who has said he will sign it into law.
The bill includes exceptions for what it defines as medical emergencies, such as cases when the mother's life is at risk or she is facing serious permanent injury, but not for pregnancies that are the result of rape or incest.
In Louisiana, a fetal heartbeat bill passed House and Senate committees on Wednesday with bipartisan support. Cory Stewart, the communications director for the House, told CNN that the bill will go back to the House floor next week for a final vote. If passed, the bill would go to Gov. John Bel Edward's office for his signature.
A fetal heartbeat bill in South Carolina passed the state House in April and was introduced in the state Senate, online records show.
In West Virginia, a fetal heartbeat bill was introduced in the state House in February.
In Florida, a fetal heartbeat bill was introduced and failed. The sponsor, Rep. Mike Hill, plans to reintroduce it next year, CNN affiliate WSVN reported.
A Texas fetal heartbeat bill formally died last week after it failed to win initial approval by midnight, the Dallas Morning News reported.
States adding abortion protections
At the same time, states controlled by Democrats have moved to add abortion protections.
New York passed a law in January that protects some late-term abortions, saying they can be performed after 24 weeks of pregnancy if the fetus is not viable or when necessary to protect the mother's life.
The law, passed on the 46th anniversary of Roe v. Wade, removes abortion from the criminal code and protects doctors or medical professionals who perform abortions from criminal prosecution.
"With the signing of this bill, we are sending a clear message that, whatever happens in Washington, women in New York will always have the fundamental right to control their own body," Gov. Andrew Cuomo said.
In Vermont, the state legislature passed a proposal to amend the state constitution to guarantee the right to an abortion. Before it can become law, the legislature would need to pass the bill again next year, and voters would need to approve it in a 2022 referendum.
If approved, Vermont would become the first state to enshrine abortion access in its constitution, said Catherine Glenn Foster, president of pro-life group Americans United for Life.
