Feeling more pained than usual, third trimester...

Cobain🎸
I'm about 7 mos pregnant. Having a boy 🙄 But I'm I'm also feeling really crippled today. I've had bilateral sciatica since the beginning of the second trimester and have had to endure a lot of pain and some days limited range of motion. Today my hips hurt, but not on the sides and in buttocks area. Instead they hurt near my groin area in the front. Quite painful the last couple of hours. When I'm standing and lift/bend my leg, I feel a lot of pressure and pain there. It makes me a little nauseous actually. I assume it could be my uterus is engorged and stretching?? And also some pressure on my hips from weight gain. Do any of you think you've experienced what I'm experiencing?? Husband will be home soon, maybe he will rub my lower back 😌
