I'm expecting identical twin boys in April. Have been having scans every 2 weeks and yesterday had my 18 week growth scan.
Both twins are fairly equal when it comes to their measurements except for their AC where there is a difference of about 15mm. The women said it was nothing to worry about just yet but needs paying a close eye on. The thing is the last scan they only had an AC difference of 4mm and i'm worrying this gap is widening and could be an early sign of TTTS?
Anyone have any experience of this? Am I just being paranoid?
I can't advise on TTTS, just wanted to say that my DTs had different abdo measurements. In fact they would take turns at who had the bigger measurement, I'm not sure if it had anything to do with how much amniotic fluid they'd ingested?
Anyway they often had more than 10mm difference in their measurements, and they are just fine.
