New to the twin thing! 🥳 These have to be identical right?

The birth center I went to did my first ultrasound and they aren't used to seeing twins. I haven't seen my new OB yet to find out any details but from my own research they look like they have to either be Mo/Di or Mo/Mo. Anyone else have a guess?? I am going crazy waiting to find out in a couple weeks. I know the pictures aren't the best but they struggled to see both at the same time. I never saw the thick separation band during all my scans that I see online in Di/Di so I assume that means identical?? We think these pictures are about 9 weeks.
