Maybe see a chiropractor? My midwife suggested that both ds1 and I schedule an adjustment because ds had sticky shoulders and I was having sciatic nerve pain during the birth. (it'll have to wait till the budget can take it though!)
I think pelvic pain is pretty normal... the bones/joints are designed to spread and loosen to facilitate birth and then it takes several weeks/months for joints to restabilize. So feeling some discomfort, especially if you did a lot of squatting/pushing makes sense. However, if it gets worse or doesn't seem to be improving you might ask your care provider. I had some odd pain/discomfort/pressure along the front of my pubic bone (especially uncomfortable during urination) after dd2's birth and it eventually turned out to be a minor pelvic organ prolapse.
