Just came back from u/s, the doc guessed the genders but it wasn't for sure, so I will have to confirm next week at a private place.

I can't remember which twin is which, the doc isn't really all that patient-friendly, and doesn't say much. I have a 20 week u/s that's gonna be very extensive, for like 2 hours, with a more specialized sonographer. I guess it is called the anatomy scan.
