Long story short- I am just shy of 7 weeks with ID twins. Wondering at what point did others find they were having either di/di or mono/di as opposed to mo/mo. Nothing is visible yet, but the Peri says it's early. From the u/s pics I've seen online Di/Di seems pretty apparent. I'm very scared but he says we will know by 12 weeks. I am eager to know what others have experienced as this is all so new and overwhelming to me.
