How early on in pregnancy is severe pelvic pain considered SPD? I've read that the loosening in the pelvis that causes SPD can be normal right before labor, but I can't find anything specific on when is considered "right before". When I read the symptoms of SPD, it sounds just like what's going on with me, but I'm 39 weeks 2 days along, and am not sure if I shouldn't be too concerned at this point. I have my regular appointment tomorrow, but should I be concerned and talking to my Dr before that?
