A 2015 study published in Endocrinology found that stress in the first trimester can actually affect the microbes that reside in an expectant mother's vagina. These microbes are transferred to the newborn during vaginal birth, resulting in changes to the little one's gut microbiome and brain development. In turn, the affected microbes impact the infant's immune system and metabolism. Scientists believe that the altered gut microbiota is linked to a greater risk of neurodevelopmental disorders, including autism and schizophrenia.
I had huge huge stress in first trimester now 29 weeks. Don't know how did I get to read this but i freaked me out totally. Anyone knows something about this?
