Random low belly pain

I keep having very brief sharp pain in my lower belly. Is it round ligament pain? I just looked online and it said round ligament pain is more common in the second trimester... I'm not concerned because it's very short and usually happens when I stand up from sitting down or vice verse. Any insights or ideas or just knowing its normal would be helpful. Thank you!
