Earliest delivery

Hi mga mommies and future mommies! Ask ko lang po if kelan po yung earliest week na pede manganak? I have heart problem and currently 30 weeks. Possible po ba 36 weeks or 37 weeks pede na? Or need ko po i maximize yung 40 weeks to give birth? Just want to ask lang po. Sa Saturday pa kasi schedule ng OB heheh. Thanks po sa sasagot. #1stimemom #firstbaby #pregnancy #advicepls
