"Lightning Crotch" in Second Trimester??

I'm a FTM and have been having episodes where a random shooting pain goes to my crotch/tailbone area.  I had heard of lightning crotch and googled it, read the description and thought "Yes! This is it!"  However, all of these articles say that it's in third trimester close to when you deliver.  Has anyone else experienced it this early??
It's not often, maybe twice a day.  I'm also having round ligament pain which feels different. 
Thanks!! 😊
