How many is to many??

Stephanie
Hi ladies! I'm currently 23 weeks pregnant. I've been having Braxton hicks contractions for a few weeks here and there but today I've had a lot! Maybe like 30 if I had to guess. They are not coming regularly but I'm getting a little nervous because of how many I've had... I know I should call my dr if I'm concerned but it's 9:00pm here right now and they are not open. I will call in the morning if they continue. Has anyone had this? Is it normal?
