Ramzi says girls implant on the left I thought. So yours is showing right but mirrored therefore actually the left suggesting girl. I had an early scan with 2 of mine. FWIW, Ramzi was correct for both. He's a paediatrician so there must be some scientific basis there.
External scan is just mirrored so what looks like the left as you see it is actually the right. Yours is sort of bottom slightly right. Roxx1516's is clearly on the right as you're looking at it. It's mirrored across the vertical so yours is actually bottom slightly left and hers is clearly left. I think Roxx is definitely having a girl according to Ramzi. Lolo, I think yours is also a girl but less clear cut; again according to Ramzi. Have the harmony test then you'll know for sure by about 11-12wks.
Lolo, not too far on for Harmony. You can have it at any point in of after 10wks. But if you're already 16wks then have a cheap scan to check the sex. The gender (sex) ones are far cheaper than a private diagnostic scan. Roxx, yours in on the right in the scan but if it was an abdominal scan rather than a vaginal one then the picture is a mirror image of the actual womb. So the pic shows right meaning it's actually on the left.
