Are you considered a Mom

So I had a chemical pregnancy and for those few weeks I had my positive I was over joyed. Unfortunately it came to an end. My nieces did ask Me if it makes me a Mom. I said I didn’t know because I didn’t give birth to a baby after all. They cheered me up and said it’s ok your like a Mom to us. It made me both sad and happy. Would you consider yourself a Mom after a chemical pregnancy or a miscarriage?
