Fraternal twins sharing a placenta?

I had my NT scan today I'm 12w5d and the tech could only see one placenta. I've had monitoring since week 5, and until last week they've been in their own little gestational sacs. For the last 7 weeks, I've had doctors and nurses tell me not to worry as if that is possible because I'm having the "best" kind of twins di/di. So now I'm a little freaked out. I don't really understand how the two gestational sacs merged together and only 1 placenta came into existence.

Has anyone else experienced this? Could it be they have their own placentas, but those also fused when the gestational sacs fused? Is that any more risky than two separate placentas? My next appointment is not until next Wednesday and Dr. Google is a terrible substitute. Even if they are considered mono/di, I know it's not the end of the world, but it's an added stress I was not expecting and something I did not think could happen with fraternal twins.

    Hm. I don't know a ton about this, but I had di/di twins whose placentas ended up fusing. I have no idea when that happened though; I just know the tech referred to separate placentas at the first u/s (11w5d) and at least once or twice after that, but at

    My twins were di/di but around 14 weeks the u/s showed only one placenta (no differentiating was possible).  As my NT scan clearly showed two we figured they fused although there was no way to tell until delivery. 

    At delivery it was c

    Thank you, both! That is helpful. I didn't think it was possible for di/di twins to become mono/di, but despite my several questions and obvious concern over one placenta, the tech never mentioned that it could be two placentas that fused together. I'm ha

    My twins are di/di and it was really obvious at my first u/s at 78weeks. By my a/s at 19w, the membrane was there and you could see the "twin peak", but they didnt look nearly as "di/di" as they did early on.

    My boy/girl twins had their placentas fuse together.  In retrospect I should have know when it happened because Baby A had been the bigger one all along and then she wasn't.  Baby B ended up being a pound heavier at birth when they had been with
