subchorionic hemorrhage

i’m 6 weeks today and i started spotting. went to the doctor got my blood taken and my beta was great. got an ultrasound heartbeat was 117 and i was measuring perfect right on 6 weeks. they diagnosed me with a little subchorionic hemorrhage. they said it’s very little and should go away on it’s own. has anyone went through this?? i’m just afraid this is my first pregnancy
