Need some advice

So since last night, out of the blue, i started getting a pain on my left side. Kinda like where my hip is but more towards the front too. As the night went on and got harder to walk or move a certain way. Before bed I couldn’t even lay or roll over the pain was so bad. I woke this morning to the same pain but now I have lower belly pain on both sides and in my back as well. My legs feel heavy but aren’t swollen. I’m only 19 weeks. Is this still considered round ligament pain? I have my anatomy scan Tuesday so I will bring it up but I’m terrified that at any moment I’m going to have this baby or something. I still feel little movements and the Doppler showed a healthy heartbeat behind my belly button.

This is where the pain is. It’s pretty constant but sometimes I’ll get a spasm that will make it feel worse for a second. It almost feels like a pulled muscle but I haven’t done anything super strenuous especially not before this pain began. Normal?!
