First ultrasound, should I be worried? 9 weeks

Everything with baby looked great. Measuring exactly how far along I thought and heartbeat was 180. 
My concern is they said they see a mass on one of my ovaries! They aren't having me follow up with ultrasound until my 20 weeks which is still 11 weeks away so that makes me think that they aren't worried but how can I just ignore?? My report said "probable right ovarian cyst and ovarian mass" I also have a cyst on the left that they say is where I ovulated. Another part of the report also says "the right ovary has an anechotic, septated appearing cyst. This may represent a hemmorhagic ovarian cyst vs. an ovarian neoplasm. The right ovary also contains a heterogeneous mass. This is of unknown etiology." 
Please any insight would be great!!
