Braxton Hicks?

Has anyone experienced Braxton Hicks yet? I have once or twice but then last night I knew for sure it was a Braxton Hicks contraction. I’m 18+6 and fairly certain it’s common since we’re pretty far into our second trimester. Just wondering if anyone else has had them too. Also, if you’ve had them in a previous pregnancy, how close to your due date (or past) did you deliver?

Thanks!!
