I technically am pregnant with mono/di twins. They share a placenta, but are separated by a thin membrane. Everytime I've had an ultrasound they've been separated like this picture 👇

But I went to get a gender determination scan about a week ago and it looked like they were on top of eachother how this picture shows 👇

I haven't gone back to my actual dr yet & won't until next week, so I'm just worried that maybe the membrane has ruptured etc. Has anyone experienced this? Is this normal for twins that are supposed to be separated to still look like they are touching each other?
