Pregnancy at 7 weeks' gestation. CRL (crown–rump length) corresponds to 6 weeks. There is a heartbeat on the ultrasound. The shape of the gestational sac shows pronounced deformation. Can someone tell me if this is anything serious? Ultrasound conclusion: progressing pregnancy. Threat of pregnancy termination. Awaiting comments. Thank you all in advance.
