Vasovagal reaction? in Life of a Mama Cat

I went to Huntington today for a baby appointment while I been here I been having abdominal pain which is Braxton hicks with me having placenta previa I decided to get checked out. The doctor decided to try to use a speculum to check everything i had a vasovagal reaction. I went numb got dizzy almost passed out and tried to throw up. The RN appeared confused as I am. My response to the surge of pain stopped her from accidentally breaking my water. The nurse put a cold rag on my head and neck and had me breathe through the shock of almost passing out. They gave me a muscle relaxer. I am so sleepy I couldn't even drive home tonight. Anybody else ever have vasovagal reaction before?
