Round ligAment pain?

Bre • ✨my year

I’m 19 wks + 4 days and in the morning I was feeling fine. I sat at the computer for a bit and started to have low back pain. I laid down and the sides of my belly, kinda inline with my hip would be, started hurting. Is this what round ligament pain feels like? Anyone feel like they’ve gone through a growth spurt this week?
