Mo/mo Twins?

Sariah

I made an earlier post because I found out I'm having twins today.

I'm a little worried as I'm already high risk( lupus), but I'm wondering if anyone has been diagnosed early with mo/mo twins to later find a separating membrane.

If so, when was it visible?

I've read all of the scary stuff you're not supposed to read and now I'm hoping for that membrane.

I'm 6.5 weeks, btw.
