Period cramps?

I’m experiencing dull like period cramps in my lower pelvis. It reminds me of how my period used to be because I’d never get really strong cramps. The cramps wouldn’t be painful just throbbing. I’m not sure they’re cramps though because my pelvis has been hurting from me sitting up too long as well.

It could just be pain from my pelvis because of the pressure from the baby. I’d assume if I were having period cramps they wouldn’t originate from my pelvis like they did before getting pregnant because my uterus is no longer in my pelvis. I’m 37+4 and haven’t had any Braxton Hicks. Honestly I’m worried I’ll never go into labor at this rate and I know it’s still too early.
