Genetic Testing

Just received my genetic gene test results back everything came up negative except I am a carrier of 2 spinal muscular atrophy genes (SMA). Getting my husband tested to break down the numerical chances of having a baby with SMA. This hit me hard cause it wasn’t expected and we all dream of having healthy babies. How do you stay positive and not worry or constantly think of the unknown. I want a healthy baby boy more than anything. Do you choose to do genetic testing or have you been identified as a carrier for SMA?
