Governor Rick Perry has signed the abortion bill into law on Thursday morning.
The bill, HB2, passed both chambers of the state legislature last week after a filibuster in the Texas Senate kept the bill from being passed during the first special session in June.
Protestors could be heard outside the room chanting "shame" as the bill was being signed.
And now, the question is when - and how - the bill will be implemented.
Most of the bill - banning abortions after 20 weeks, restricting abortion-inducing drugs like RU-486, and requiring doctors who perform abortions to have hospital admitting facilities within 30 miles of an ambulatory surgical center - will go into effect 91 days after the special session ends.
That will be mid- to late-October depending on when Governor Perry ends the session.
The other major part of the bill limits abortions to ambulatory surgical centers.
Under the new law, only five of the 42 abortion clinics in the state currently meet the requirements of ambulatory surgical centers.
Those five centers are in Dallas, Austin, San Antonio, and Houston.
The state's other 37 abortion clinics would have until September 2014 to comply with those surgical center requirements.
But experts have said that will be tough to do, because the major difference right now between many of the state's abortion clinics and ambulatory surgical centers has to do with how the surgical centers are constructed and involves details like how wide the halls are.
All of these implementation dates depend on whether legal challenges are filed in court.
The Texas ACLU has already told The Texas Tribune they're planning to fight to make sure the law isn't implemented.
