Severe pelvic pain

I'm 20 weeks pregnant and my pelvis... oh goodness. It started when I was in bed and the next morning it would hurt. And then, it started hurting every time I moved in bed. Now I can barely move or get out of bed and not be in excruciating pain. Now I can't even walk around a store without my pelvis feeling like it's going to split. I'm sure the baby is fine. Feel her kicking well. This is my second baby. Never had it with the first. Any words of wisdom to comfort myself? Tried baths, pulling knees together but every day it's getting worse. My midwife just told me to bear through it. :(
