Round ligament pain?

Grace
I've been experiencing what I'm pretty sure is round ligament pain 5-6 times a day but just on my left side. How long does this usually go on for? Should I call my doctor about it tomorrow? I'm 18w1d and It just started a few days ago, but it's been the most constant today. 
On the plus side I felt baby give a real kick (as opposed to flutters) today for the first time, so that made me day! 💕😊
Thanks in advance for your insight and information ladies!! ❤
