I had scans at 20, 30, 34, 36, 38 and 40. Low Papp-a too.
but my baby was average until 28 and then started dropping centiles. She was born at 2nd percentile by induction.
so they are definitely worried about your DD, as her centile is very low.
tell her to keep monitoring baby”s kicks, there is a risk of still birth, and go for an assessment for any reduced movements, even if she’s not sure, it’s better to go and check.
it’s very good they are checking her weekly. They might induce her earlier, or she can have an elective CS if she asks for it, if they consider it’s too risky to wait longer.
I hope she’s been taking 150mg daily aspirin since 12 weeks? Especially as this is her 2nd, the dr would have known to put her on it. If they haven’t it’s good to know and ask for it if she goes for a 3rd baby.
