ultrasound concerns!!!!!!! (urgent)

hey guys so I just got my ultra sound results back and it says there is a gestational sac (4.2 cm) that contains a yolk sac measuring 2 mm. there is a small embryo with crown rump length of 6.8 mm (equal to 6 weeks 3 days) but they didn't detect a heart beat and adjacent to the gestational sac is a hypo echoic fluid collection measuring 16 × 7 × 8 mm suggesting a subchorionic hemorrage. what does this mean and should I be concerned????????????? please help!
