CAS 3D/4D ultrasound

Hi mama! Yes, CAS (Comprehensive Anatomy Scan) is best done before 28 weeks kaya perfect timing mo ngayon at 22 weeks, that's when they can see everything clearly para sa detailed assessment. For 3D/4D ultrasound, walang strict cutoff pero honestly, a few of us mums did ours around 28-32 weeks kasi mas clear na ang baby's features at mas developed na, though you can do it anytime really, ask your OB kung best time para sa inyo based sa baby's position at amniotic fluid. Either way, best to confirm the exact timing with your doctor since they know your case best, pero sounds like your plan is spot on! Congrats sa buntis mo!
