Scary ultrasound. Need prayers

Casey
So I went and had an eight week ultrasound done and found out my yoke sack is enlarged. My midwife isn't too worried about it but did mention there is a small 10% chance I may miscarry. I'm so scared and the next 2 weeks are going to take forever. Have to go in again on the 5 of July to have another ultrasound done to make sure baby is still there with a heartbeat. Please any prayers are appreciated.
