Almost 2 weeks postpartum!

Hey ladies, so I delivered my baby boy on December 7th

Vaginally and yes I received an epidural. This is my third child the other two also vaginal births. Also two weeks postpartum and I'm still in a lot of pain when I move around, especially when getting up from sitting. My whole pelvis hurts. I was sent home with 800 ml ibeprofren but they do not work at all 😞. I never experienced this with my other two kids, never even asked for pain meds after delivery and this baby was the smallest and I came out the quickest and easiest.. any of you other mothers experienced this? Should I be concerned?
