Round ligament pain?

I’m 31 weeks and 4 days. I feel like a muscle ripped or is ripping and it hurts a little. Usually only around the belly button. Never felt this before. First time being this far in my pregnancy. Not sure if it’s round ligament pain or not. I have an apt this coming week with my dr so I will for sure be mentioning it. But just wondering if anyone else experienced this and has positive results. Thanks loves.
