When does round ligament pain start and what does it feel like?

KP

I’m 13 weeks today, last night when I bent down my stomach hurt really bad for a second. Last night I woke up in the middle of the night a couple of times with a sharp sort of stomach pain. Didn’t last long, almost felt like I was punched in the stomach. Is this round ligament pain? Is 13 weeks too early? The pain is kind of scaring me so hoping it’s normal.
