Almost Died

Two of my dogs and my mom and I were attacked by a cow tonight. I watched in horror as the cow drug around our smaller dog like a rag doll. I got our big dog away and then the cow was charging my mom and me. (Very condensed version of the story). Neighbors came running to our screams and we were finally able to get the cow chased away. (It would have ended badly had the neighbors not shown up to help). We are all fine minus a few cuts and bruises, but it was about 30 minutes of extreme adrenaline and stress. Took me almost two hours to calm down. I’m just wondering if it could cause any harm to my baby? I’m only six weeks and I know stress is very bad for the baby, but I was wondering if it was just extended periods of stress or could be caused by one traumatic event?
