The new law outlaws abortions in the state at six weeks into the pregnancy.
And while some in Hollywood are calling on a boycott of Georgia, Milano is calling for a boycott of sex. "Until women have legal control over our own bodies we just can not risk pregnancy", Milano tweeted.
Milano told The Associated Press on Saturday that "the stakes are never higher than right now" because the laws are "outrageous" and could be decided by the U.S. Supreme Court, which conservatives hope will overturn Roe v. Wade. I'm calling for a #SexStrike.
By Saturday afternoon, #SexStrike and "Alyssa Milano" were two of Twitter's top 10 trending topics, and Milano's tweet had close to 25,000 likes and almost 9,000 retweets.
Other actors have also voiced their support, as have the heads of several independent production companies. For her part, she hasn't decided yet how long she will forgo sex.
Kompany fires City back to top
If both teams win their matches on the final day of the season, this Sunday, Man City will lift the trophy once again . The pair won the German league and cup double together in 2011-12, the last time Dortmund won the Bundesliga title.
Sound OFF on all of this social media chatter and more, all in the comments (below)... Governor Kemp's "foetal Heartbeat" Abortion Law is an unconstitutional effort to further restrict women and their health providers from making private medical decisions on their terms.
Milano is not the only celebrity to use star power to protest the new law. The law is seen as a near-ban on abortion, as many women don't realize they are pregnant until the fifth week, meaning organizing an abortion before the cut-off would be very hard.
Milano said the criticism didn't bother her and that her tweet was having her desired effect, "which is getting people to talk about the war on women". The latter stems from the passing of a new law within the states of Georgia and five other states.
Georgia offers generous tax credits to attract TV productions, and in recent years the state has won a lot of business from the film and TV industry. "Pass it on", she tweeted.
