Your sonographer will use this information to try to work out if your twins are identical. Your first scan is likely to be your dating scan, between 10 weeks and 13 weeks plus six days (NCCWCH 2011, NICE 2011). This may also be the first time you find out you're expecting twins at all, so there'll be a lot to take in.
Yes at 6 weeks it is possible to miss twins. Most u/s's that early are looking for heartbeats and the heartbeat is suppose to be visible by 6 weeks however sometimes it can be 7 weeks before it shows. So if you had an u/s at 6 weeks and it showed one hb and have another one a few weeks later you could have 2 hb's then.
