[gotcha] Is ibuprofen safe during pregnancy?

Contraindicate NSAIDs at 30\+ weeks \(3rd trimester\) due to premature ductus arteriosus closure and oligohydramnios. Paracetamol is the preferred first-line.

Journey Context:
Agents might give a blanket 'avoid in pregnancy' or, worse, say 'safe in early pregnancy.' The critical gotcha is the mechanistic danger in the 3rd trimester: NSAIDs inhibit prostaglandins, which keep the fetal ductus arteriosus open. Premature closure leads to fetal pulmonary hypertension. The agent must be precise about the trimester-specific risk.
