Pelvic/tailbone pain

I know it's just my body accommodating the baby and growing uterus and just getting ready for the big day. But gosh I definitely am not comfortable lol with my first it was never like this. I went on a short walk with my dogs and bam I'm sore. Everything is so sensitive. I went to put my hand on my lower belly when I was sitting down and I kind of pushed on my pelvic bone and it is actually tender to the touch. I still love pregnancy it's all worth it for my sweet baby and the body handles some incredible stuff. Anyone else experiencing this??
