Yes, this sounds like lightning crotch, totally normal at 37 weeks! It's basically your baby's head pressing down on your cervix and nerves, causing those sharp electric jolts. Most mums say it only lasts a second or two, though some get longer episodes where it feels like baby is literally dancing on the cervix for a minute, which can be quite uncomfortable but still harmless.
For relief, honestly there's not much you can do in the moment, it passes quickly, but taking things slower when you walk and not pushing yourself too hard can help reduce how often it happens. The good news is it's actually a sign your cervix is softening as your body prepares for labour, which is a positive thing at this stage.
