Hi, my wife's first ultrasound at 6w 6d showed a gestational sac, yolk sac and embryo measuring 2.3mm dated at 5w, and no heartbeat. We did a repeat scan at 8 weeks (2 days ago) which revealed a growing gestational sac and yolk sac measuring 8w, but no sign of an embryo or a heartbeat. The second ultrasound was performed at another center and, to my untrained eye, the images do not seem as clear as our first scans.
What is the likelihood that this pregnancy will progress normally?
If it will not progress, what criteria should we consider to choose between waiting for a normal miscarriage, or to opt for a medically induced miscarriage (drugs or D&C)?
