31 weeks, 2 days, is anyone else going through this?

Lately I've been having a LOT of pain from my hips down. Even just laying still in bed, my lower legs (knees down) hurt. Rolling over, the pain in my pelvic girdle and inner thighs is almost excruciating. Walking has become an act of willpower. I've spoken to my OB/GYN and she told me that this is normal and just to use a maternity belt. The belt helps somewhat, but I can't wear it 24/7 and it doesn’t alleviate anywhere near the amount of pain to make it so I feel normal. I've been pregnant before (my last pregnancy I unfortunately lost at 36 weeks) and NEVER have I experienced pressure and pain anywhere NEAR this. Is anyone else dealing with this or has dealt with this?
