Anyone else have a hematoma?

Our first ultrasound was yesterday. Little one is due Nov. 9th. Everything seems okay so far.. a hb of 181 and all levels seemed well... however, the doctor is concerned about a small hematoma. I didn't have that in my first pregnancy so I'm a little nervous :/. We go back May 1st for another US to check on it again.
