The Supreme Court's decision to overturn Roe v. Wade, the 1973 ruling that protected the right to an abortion in the U.S. under the Constitution, has complicated matters.

Now, states are able to decide the legality of abortion, and it's unclear how exactly this will impact access to abortion pills via mail or otherwise in states that aim to ban all abortion methods.

First of all, the abortion pill is technically two pills that you take over a couple of days: mifepristone and misoprostol.

Mifepristone (RU-486), also known as "the abortion pill," is the pill the FDA approved to be delivered by mail.

Mifepristone blocks progesterone. It's a contraceptive, like hormonal birth control pills, that prevents or interrupts pregnancy.

"Mifepristone is FDA-approved to be used with misoprostol for prescription abortion up to 77 days," adds Dr. Shaw.

Planned Parenthood says a suction abortion, which utilises "gentle suction" to empty the uterus, is the most common in-clinic abortion technique.

Whether you have insurance and where you purchase the abortion pill. Plan C predicts abortion costs at $40 to $600. Without insurance, Hey Jane's abortion pills are $250.
