5 week and 4 day ultrasound showed yolk save with foetal pole, no subchorionic haematoma and a corpus luteal cyst. Ultrasound at 7 weeks 3 days showed normal YOLK SAC, FOETAL HEART MOTION OF 150BPM, ovaries normal in appearance, no abnormalities of uterine wall but 2 small subchorionic haemoatomas. One 1cm collection at the left superior aspect of gestational sac with 0.8ml collection at the right inferior aspect of the sac. Should I be concerned? No bleeding during pregnancy
