Serious Pressure- Concerned??

Kris
Hi ladies! Need some advice. I'm 32wks and lately I've been getting some serious pressure low down near pelvic region. It's not painful, just uncomfortable, heavy, that kind of feeling. I thought maybe it's BH, but again it's not painful and I only feel it down low, not throughout the entire belly. Anyone know what this might be? Should I be concerned? Thanks so much!
