My wife is currently 16 weeks pregnant. Her first trimerster scan (done at 8+ week) report was normal (single live intrauterine pregnancy). She is currently out of town (at her mom's place). By which week is the Anomaly scan (second trimester scan) is to be done? She needs to return and schedule accordingly. Just in case of serious complication and the out-dated MTP Act of our country... Need to be sure!
