Scared to try again

So I have a doctors appointment tomorrow to get my hcg done since I am experiencing a miscarriage. My bleeding is finally slowing down which makes me happy. I’m scared to want to try again since this is my second miscarriage within a year! I wish a miscarriage was never a thing and infertility didn’t exist at all. No one feels the pain you do when losing a child. Believe I’m grateful for the child I have but she wants a sister or brother at home with us
