7 weeks 3 days measuring small with heartbeat

Emma

I had an ultrasound today expecting to be 7 weeks 3 days and we saw a heart beat but baby only measured around 6 weeks 2 days. After discussing the timeline more in depth with the doctor we realize I ovulated on or around day 17 ... so a little later than “normal” and that makes it about 5 days behind. We go back for another ultrasound in a week. Anyone else have this experience??
