Sudden, sharp shooting pains in pelvis or vagina as baby moves and presses on nerves.

Medically reviewed by healthcare professionals | Last reviewed: March 2026

📅 When It Occurs

Third trimester, especially last few weeks

📊 How Common

Very common in late pregnancy

Overview

Lightning crotch is the colloquial term for sudden, sharp, shooting pains in the pelvis, vagina, or rectum that feel like electric shocks. These pains are startling but brief, lasting only a few seconds.

These pains occur when your baby moves into a position that puts pressure on nerves in the cervix, pelvic floor, or vaginal area. The sensation is sudden and sharp, hence the "lightning" description, but it passes quickly.

While uncomfortable and surprising, lightning crotch is normal and doesn't indicate labor or a problem. It's more common as you approach your due date and baby drops lower into the pelvis.
