🩺Clinical Context — From a Nurse's View
Thirty-six weeks is 'early term' approaching, and many babies engage (drop into the pelvis) this week. Engagement makes breathing easier but increases bladder and pelvic pressure. The 'lightning crotch' — a sudden sharp shooting pain in the cervix or vagina — is the baby's head bumping nerves and is harmless. Visits typically become weekly now. Cervical exams may begin if your provider does them; many providers don't routinely do them before 38-39 weeks because dilation in the absence of labor doesn't change management. Discuss your provider's policy around induction — at 39 weeks, induction in low-risk pregnancies has equivalent or slightly better outcomes than expectant management (ARRIVE trial, NEJM 2018) and doesn't increase C-section risk. Going past 41 weeks increases stillbirth risk slightly, so most providers will discuss induction at 41 weeks if labor hasn't started naturally (ACOG 2014).
