CAS (Anomaly Scan)

First time mom here. Wala akong alam as in. Nakapag transv lang ako to nung first tri and pelvic ultrasound recently to reveal my baby's gender. I just read something online about CAS. I asked my ob bakit hnd ako nirecommendan ng ganito to see if my defects or abnormalities baby ko pero sabi its too late na daw kasi 8 months na tummy ko. 33 wks and 3 days to be exact. Ano po masasabi nyo about this? #firstbaby #pregnancy
