Ultrasound at 4 weeks

Becca

I had one done last Wednesday and my hcg level was about 700 when they did a vaginal ultrasound. They didn’t see a sac or anything. My level more than doubled by Thursday so they are sending me for another vaginal ultrasound this week. He said he expects to see a sac and a yolk sac. I’m so nervous. Anyone else experience the same thing?
