Stomach herniation

I am 11 weeks pregnant and had to get an ultrasound last week. I have a tilted uterus and they could not find the heart beat with out ultrasound. The ultrasound showed a heart beat of 168 and the baby was moving around like crazy! I just found out yesterday that they are concerned about a stomach herniation. I go back next week to see a specialist and get another ultrasound. I’m hoping everything will have resolved by the , but I am still very nervous! Anyone have any experience with this!
