Second pregnancy pain (tmi)

I have so much pain already. I'm only 31 weeks and my whole lower half is crippling pain like 24/7 hips, crotch and legs. It hurts to stand, hurts to sit, hurts to lay down. I feel like I can't poop because if I push just a little bit my crotch hurts and feels like I'm going to push out the baby. This is my second and I had none of these issues with my first so I don't know if it's normal or not. I have an appointment Wednesday morning but just wondering if anyone else is going through this? 🙃 thanks in advance ladies!
