37+4 - is this amount of back/side pain normal? Round ligament pain?

FTM. I’m in absolute agony with middle side pain which radiates to my back (right side). Today I’ve been keeled over in pain and it’s making me extremely nauseous. I’ve also got some numbness in my upper thighs as well.

My BP is fine, 115/84 and I don’t have any pre-eclampsia symptoms so don’t think it’s this and I’ve not been at risk before.

I’ve had two episodes of simile pains this pregnancy, once at 26 weeks and again at around 30 weeks, but not this bad. It was put down to ligament pain but no midwife or doctor really knew what it was.

Can this really just be a bad case of round ligament pain? It’s consistent and doesn’t go away. I’m reluctant to call triage unless I really need to, as they haven’t been able to do anything for me in the past.

I’ve also read it can be a sign of early labour but I’ve not had any contractions or any other labour signs at all?

Has anyone else experienced this agony?
