"lightning crotch" feeling too early??

24 weeks preg with my second.. a girl!😊 I have been getting "lightning crotch" super regularly all this week and it's starting to kind of worry me? I got it around 32+ weeks with my son a couple of times but not like this. I got pregnant 5 months postpartum after my son was born so I'm thinking that might be why it's so early? Anyone else? Not sure if I should even worry or not. Just seems early.
