Iowa Gov. Kim Reynolds (R) said Saturday that even though she has signed the nation’s strictest abortion ban into law, there is still more work ahead.

“We know that our work is not done, that we must continue to work together to change the hearts and minds," Reynolds said, according to the Des Moines Register. “But I’ll tell you what, we’re not slowing down, we’re not going to stop. It’s a fight worth fighting."

The Register reported that Reynolds touted the new legislation on Saturday during the Iowa Faith and Freedom Coalition’s annual event.

"We are No. 1 in the country when it comes to protecting life,” Reynolds said. "I believe all innocent life is precious and sacred, and as governor I pledge to you to do everything in my power to protect life."

Reynolds said she planned to sign Iowa’s six-week abortion bill into law earlier this month. The governor reportedly received a standing ovation on Saturday for signing it.

Also known as a “heartbeat bill,” the measure requires women seeking an abortion to undergo an ultrasound before the procedure to determine whether the fetus has a heartbeat.

Opponents of the law say that it would prevent many women from having the procedure before they even found out they were pregnant.

The bill is expected to face legal opposition; Planned Parenthood of the Heartland has promised to file a lawsuit.

Other states have tried to implement similar restrictions on abortions, but the legislation was blocked by the courts.

However, many conservative state lawmakers are trying to pass new laws that could prompt a review of the 1973 Roe v. Wade decision on abortion.
