Shocks in vagina and back?

kay👨‍👩‍👧‍👦

So I've had lightning crotch over the past few weeks but today when I got my lightning crotch I also get some jolts in my lower back. Is that from nerves down there that make both hurt? And does anyone know if that will increase my odds of having back labor? I've heard that's the worst. I didn't have back labor with my first so I'm just trying to get myself prepared for this shit. 😂

Thanks ladies ☺☺☺
