Girls, good evening. Maybe someone knows. What should I do?

Girls, good evening. Maybe someone knows. What should I do? I registered for prenatal care in Nur-Sultan and I'm being seen here. But I have a peasant farm — consider it a sole proprietorship — in another region. I pay my pension and social contributions from there. How do I arrange maternity pay? Do I need to go there to register/attach, or can I get a sick-leave certificate from here?
