Round ligament pain?

Danielle • MC in May 2017; Chemical in Nov 2017. Mommy to our rainbow baby Rowan 🌈 ; Casually ttc for baby #2

Can anyone describe what this feels like and when it started? I'm trying to figure out if what I'm feeling is round ligament pain or just muscle soreness. I'm around 5-6 dpo. I had a miscarriage in May and didn't experience this with my first pregnancy. Thanks!
