Currently, 13 states have passed “trigger laws” banning abortion that would go into effect immediately if the Supreme Court overturns Roe. Four states, Alabama, Louisiana, Tennessee and West Virginia have amended their constitutions to prohibit any protections for abortion rights.
Alabama, Georgia, Ohio, Iowa, and South Carolina have passed laws restricting abortion that have been defeated by courts. Those laws are likely to be re-instated as soon as Roe is overturned. Also at that time Florida, Montana, Indiana and Nebraska are likely to quickly pass laws restricting or banning abortion.
The map below shows where states will be if Roe is struck down, prior to more states passing new abortion laws. From Axios.com:
