Multiple scans in first 12weeks

Please post!! If anyone has had more then 1 scan in the first 12 weeks can you please post it , my last scan(almost 3weeks ago) baby/sac was in a weird position and they didn't bother measuring it and I have to go back for another scan(2days to go) but I'm worried it's going to be in same place and I'm not going to get a accurate messurement resulting in another csection due to large baby that technically wouldn't even be large if was measured properly
