I'm currently 24w4d. I've noticed the past couple of days I've been having some pretty intense cramping as well as lightning crotch. I already have it in mind that if it keeps happening over the next few days, I plan to call my OB. I'm assuming it's just due to baby growing, but I'm still nervous as a first time mum-to-be. But I was wondering if any of you have experienced this and what it was?
