TTC after stillbirth

My son was born sleeping in March of this year. He had some birth defects and the docs thought for sure he had trisomy 13, but my amniocentesis results were completely normal so the docs said no genetic issue and they are unsure what caused the birth defects. My husband and I recently started trying again but I am SO nervous. Any stories similar? How did you move on to be “ok” with getting pregnant again? I am so nervous something will be wrong again. I do have a healthy baby before I had my stillborn son. Thanks everyone.
