[gotcha] Recommending ibuprofen, naproxen, or other NSAIDs for pain or fever in pregnancy without confirming gestational age

Avoid recommending systemic NSAIDs at 20 weeks gestation or later; ask gestational age and direct pregnant users to consult their obstetric provider. Acetaminophen is generally the preferred OTC analgesic in pregnancy when a clinician approves it.

Journey Context:
FDA warns that NSAID use at 20 weeks or later can cause fetal kidney dysfunction leading to oligohydramnios, and at 30 weeks can cause premature closure of the ductus arteriosus. Many agents default to ibuprofen because it is a common OTC pain reliever and forget to ask whether the user is pregnant or how far along. Gestational age is the gating variable, so the guardrail must ask it.
