I just had my private reassurance scan. I'm 7+3 according to dates but measured at 5+6! The sonographer was very optimistic saying 'this happens all the time' and I won't really know when I conceived so may be less than I think. She was trying to be very reassuring which was nice to hear but I'm just not convinced. My lmp was 22nd Aug and positive OPK on day 15. The scan (which was transabdominal) showed a sac and york emerging but that was it. Im just left very unsure. Repeat scan in 2 weeks. Anyone been in same position and all been ok?
