Painful pelvis after jogging?

I am 32 weeks pregnant with my 1st. I am very active and been working out my whole life. I have continued to workout and jog my whole pregnancy so far. My doc said it was completely fine for me to continue. But tonight while I was jogging, when I stopped I could barely remain standing because of this sharp pain in my pelvis area right near my vagina. It’s so bad that I can’t even stand up to put pressure on my legs. What do y’all think this is and did you experience this feeling? I am currently sitting in the back of the gym waiting for the pain to release. Note: it doesn’t hurt when I’m sitting. Once I stand up and bend my legs to move, my vagina bone hurts sooooooo bad! Help!!!! Thanks in advance!
