TTTS in mono di twins

Jen • Mommy to a 7 year old boy and 4 month old twin boys!
Anyone here have ttts with their mono di twins? Just had an ultrasound yesterday at 14.4 weeks and babies had a fluid difference. Doc said it could be the start of ttts and I need to have it rechecked next week. I'm extremely nervous and looking for any ladies that are in a similar situation!
