Empty empty sac???


I should be about 8w5d pregnant with my first baby. I went today for my nurse visit and she did a quick abdominal ultrasound in her office where a sac showed but no baby. She said this can be normal so she’s sending me for a transvaginal ultrasound at 2:30 today. I’m worried sick, has anyone has a good turnout? I’m praying for a miracle but preparing for the worst. Please send positive thoughts and prayers and any advice.
