Hi there. Im in the same predicament as yourself at the moment. I had a scan last week that showed just the sack. It was very hard to understand because my due date should have been round 28-30th April but the scan showed 7 May. I went again this week And and still nothing so have to go bak in 2 weeks time. I feel nausea all the time though but it is concerning and I know how u feel. Heads up and hope we both have good news soon xo
