Hello ? Today I had an ultrasound at exactly 8 weeks. There was a large hematoma, just as it was, and it remained that way. For two weeks, I took the prescribed medications. The injection was given but nothing changed. The baby's heartbeat has grown well. The doctor says there is a risk until 16 weeks. They prescribed bed rest and medication. What if the hematoma doesn't go away? I'm worried ?
