subochronic hemmorage

Skye
Today I am 10 weeks 1 day and on Friday I ended up in the ER for pain and dehydration they gave me an IV and did an ultrasound. They mentioned Hyperemesis gravidarum but I'm not to sure about it. They also said there is a subochronic hemmorage by the baby they found when they did the ultrasound. They said it's nothing to worry about but it makes me so nervous. Does anyone else have either of these?
