I went through IVF for both my pregnancies. With DD I had a dating scan at 7 weeks, the NT scan at 12 weeks, morphology scan at 20 weeks, 4D Scan (not covered by Medicare) at 26 weeks and then a scan at 34 weeks to check position.

With this pregnancy I had my 7 week dating scan, a scan at 9 weeks (my first OB appt), NT scan at 12 weeks, Growth scan at 16 weeks and morphology scan at 20 weeks. I'm also scheduled for scan every 4 weeks with my last at 36 weeks to check and make sure the twins are growing and to make sure there is no problem with the placenta and fluid levels.
