I had my anatomy scan done last week (22 weeks w/ di/di twins) and a nurse from my OB’s office called to tell me that there were some “discrepancies in the measurements” (whatever that means). I know Twin A was super hard to get measurements of and was expecting to have to go back for more measurements. Anyway, they are now referring me to a MFM for an ultrasound. I am now 23 weeks. What should I expect from this appointment? Does the doctor do the ultrasound or a tech? Will I get answers/reassurance before I leave the appointment?
