i had an ultrasound at 7 weeks, and all they could see was a sac and measuring 5w4d, i went back about a week later, and it was only measuring 5w2d, i eventually miscarried.

with this pregnancy i had a scan at 7 weeks, and bub was only measuring just over 5 weeks, no heartbeat and only a sac, a couple of weeks later, went back and there she was, a strong heartbeat, i was not as far along as i thought i was.

hoping all goes well for you
