2nd time around more painful?

Alison
I am 4 weeks with my 2nd and I'm already having round ligament pain, siatic pain, & I feel like the stretching and pinching pain is worse and felt earlier.  I mean no "bad pain."  Just annoying I can't cough or sneeze without knowing it's gonna hurt!  Anyone else notice it's more painful the second time or am I just noticing things more?
