On Thursday, the country's constitutional court announced that abortion of fetuses with injuries is contrary to the constitution, which opens up for a tightening of the country's already very strict abortion legislation.
Since then, thousands of protesters have marched daily through several Polish cities.
Streets have been blocked in Warsaw, and the Polish parliament has been surrounded for several hours.
The participants have been urging the government all day to come out and talk to them:
"Come out and meet us!"
sounds the slogan.
"Nobody went to class"
In the country's third largest city Łódź, today's student protest quickly grew into a full-scale demonstration with thousands of participants.
High school student Jagoda was one of them.
- No one in my class went to the lessons today.
We told our teacher that we would go out and demonstrate, she tells SVT News.
Jagoda says that at first she was worried about participating:
- I was scared because of the pandemic, we are constantly told that we have to stay indoors.
But then I thought that if I will not fight for my rights - then who will?
"A serious crime"
The government has repeatedly gone out and warned the public not to participate.
The Polish Prime Minister has called the demonstrations "barbaric" and the ruling party leader Jarosław Kaczyński said in a statement on Wednesday that those taking part were spreading danger and committing "a serious crime".
- Authorities have not only the right but the duty to oppose this type of activity, he says.
Jagoda does not think the criticism of the government is entirely fair.
- It could have been justified criticism, but they themselves are trying to get through these changes in the middle of a pandemic.
There is no other way for us to show our dissatisfaction, she says.
Jagoda hopes the protests will lead to a change, but she is not convinced.
- Nothing will happen in the next few weeks.
But maybe the government will eventually reconsider the decision - if we persevere, she says.
