Anyone got experience of possible TTTS at 16 weeks?

L

I just had a scan because at our 13 week scan the sonographer wasn't 100% sure if it was only one placenta. At today's scan (16 weeks tomorrow) they said it definitely is one placenta (so identical, higher risk) and twin 2 is 15% smaller than twin 1. They also saw some gaps in the Doppler reading from the umbilical cord. I've got to go back next week and the consultant said it might just resolve itself but that it could also be early sign of twin to twin transfusion syndrome. I'm really worried. Anyone else have this and it turn out not to be a serious problem? Thanks
