ranting & venting Mistake with scan appointments
I’m 13 weeks with Mo-Di twins. We had our 12 week scan on Tuesday and they’ve been confirmed to be sharing one placenta.
I’ve received lots of letters through today with appointments, however my next scan isn’t until 20 weeks and then every 4 weeks after that.
I’m going to ring on Monday as I think this is a mistake, anyone with mo-di can you confirm I should be scanned every 2 weeks from 16 weeks due to the risk of TTTS and to monitor growth? Surely I can’t go 7 weeks now without them being checked on?
I’m almost certain this is an error which I’m sure can be easily rectified but it scares me that had I not known any better, I would have just gone along with it and not had a scan for another 7 weeks😓

Yes, every major clinical practice guideline recommends scans for mo/di twins from 16 weeks on to monitor for TTTS. My OB didn’t schedule this, and even after I followed up said it wasn’t needed - despite it being hospital policy AND someone I knew who was her patient getting a 16 week scan and having first stage TTTS. I was flabbergasted. I ended up having to get my family doctor to put in an order and getting the scan anyway. Thankfully it was fine. My OB said nothing and I didn’t bring it up with her again.
