Freshman Rep. Alexandria Ocasio-Cortez blasted an anti-abortion bill that was passed by the Georgia governor on Tuesday, calling it a “backdoor ban” on the procedure.

Georgia Gov. Brian Kemp on Tuesday signed the “fetal heartbeat bill,” a measure that makes it illegal to have an abortion after a heartbeat is detected in an embryo. This typically takes about six weeks.

“‘6 weeks pregnant’ = 2 weeks late on your period,” Ocasio-Cortez wrote on Twitter Tuesday night.

“Most of the men writing these bills don’t know the first thing about a woman’s body outside of the things they want from it. It’s relatively common for a woman to have a late period + not be pregnant.

“So this is a backdoor ban,” she added.

A number of conservative states have signed similar bills to get the issue back in front of the Supreme Court with what they view as a sympathetic panel, the Washington Post reported.

In addition to Georgia, 15 states have passed or are trying to pass such bans on the procedure.

Ocasio-Cortez added in another tweet Tuesday night that the Georgia bill would leave women with no way of having an abortion in time.

“For context, this kicks in within days of a typical at-home test working,” she wrote.

“If you were sexually assaulted (stress delays cycle), took a morning-after pill (throws off cycle), or have an irregular cycle, you‘d have no idea.

“There are a TON of ways this law ignores basic biology,” she added.
