Pelvic pains at 39w2d - normal?

LM :)
I'm experiencing intense pains in my vaginal area - is this normal at 39w2d pregnant?
Its worse when i'm trying to get up from a laying or sitting position or when i walk. 
When I'm on my feet or walking I feel a lot of pressure and severe discomfort when lifting or parting my legs.
Anyone else experiencing this or have experienced it with previous pregnancies?
Thanks!
