We have been told we are having a singleton  girl but have the twin feeling from early on? I'm measuring large and started showing immediately- I do have large babies so that could be the case. At our 20 wk u/s, I have pics and my sister called out twins and now I'm suspicious- the tech asked if only one and we said yes, so not sure if she wasn't looking or if it would have been obvious? Let me add pic which looks like a 2nd baby in the background and there's a profile I have with what looks to be another face next to it. I have an appt next week so will ask but wanted to know if anyone experienced this or something similar?
