Hip Discomfort

I will be 37 weeks pregnant on 5/11. I've been having hip discomfort and this being my third pregnancy, I expected it. My question to you ladies is this: 
The strain I feel on my hip is actually not at the joint on the outside of my body, but on my inner thigh near vagina (the bone or ligament, whatever it is that leads away from that area). Anyone else have issues with this? It's only on my left side.
