[gotcha] NSAIDs recommended for pain or fever in pregnancy without checking gestational age

Before mentioning any NSAID in pregnancy, request the gestational age. At 20 weeks or later, recommend acetaminophen/paracetamol instead and refer to obstetric care; never recommend NSAIDs after 30 weeks. Only allow low-dose aspirin if it was specifically prescribed by a clinician.

Journey Context:
Ibuprofen and naproxen are first-line analgesics in non-pregnant adults, so agents and users assume they are safe in pregnancy. They are not after ~20 weeks: fetal renal dysfunction and oligohydramnios can occur, sometimes within 48 hours. The trap is that NSAIDs are generally acceptable early in pregnancy, so a blanket 'avoid' is wrong, but a blanket 'OK' is dangerous. Gestational age is the decisive variable.
