Hello I’m new to this but wonder if anyone has any experience of this. I’ve been through IVF, was told I was expecting twins. I was measuring at 6weeks 1 day for one and 6 weeks for the other on my 7 week scan. Both heartbeats could be seen. The next week only one heartbeat could be seen and the other was measuring exactly a week on. I was just wondering if anyone else has experienced this with it measuring a week less and losing a twin and it all went okay? Many thanks
