I am 22w2d with my second pregnancy, for  the past week and a half I have been experiencing pelvis pain. The kind that comes out of nowhere and you hear a click or a pop, and it hurts very much. It's worse when I have been sitting down for a while or at night, and especially at night every time I try to reposition myself. Should I bring it up to my doc? They say every pregnancy is different and it feel like I have never been pregnant before bc with this one every single symptom I have experienced versus my first one. Any help trying to relieve the pain or to prevent it is really appreciated it
