Question about losses and miscarriages

Ma

Ok have a question. I have been pregnant 6 times now and my order is as 👼👼🌈👼🌈👼. I had a chemical, ectopic, my daughter, a miscarriage, my other daughter and then another chemical. My question is do you think some women need the extra hormones from a miscarriage or a loss to sustain a full term pregnancy?
