Please describe round ligament pain to me?

I’m having a new pain, it’s quick and sharp (not unbearable) pain it’s just on my left said it comes and goes. I’m almost 13 weeks pregnant. It feels almost like a sharp muscle spasm, lasts for a few seconds then comes back again a few minutes later...started about 30 minutes ago and did it a few times then stopped. Is this round ligament pain?

I have not bleeding or anything alarming just this feeling.

I’m trying to cope with my anxieties while pregnant and every new feeling I experience just worries me.
