Yes, I had it while I was pregnant, both times. I've heard it said that the pain eases up during pregnancy, and while I waited breathlessly for it, it never quite happened. In fact, the pain was worse, as was the fatigue, but I was so scared of the meds I took as little as possible.
If you don't have access to a warm pool, find one. That was the only time I had any relief, when i was laying in the warm water.
