There are TONS of herbs and food that us women can ingest to ensure our periods happen, regardless if we are pregnant or not.
We can even extract our periods each month via a simple device we can use at home with a partner, regardless if we are pregnant or not.
Women have been aborting unwanted pregnancies for a very long time and it's not going to stop happening, regardless of any laws people try to create.
The ONLY thing anyone can actually do about this is HELP humans find a way to 100% never become pregnant via sex that has NO unwanted side effects.
Beyond that, you are just bitching about something you can not and will never be able to control.
