vintage evening formal wears sales back to 1920s

I'm 23 weeks and having lower back pain. I can barely bend over or squat down because it hurts to stand back up. I have tried a heating pad but it's not helping. When I'm having these back pains I can't lay down on my back or left side cause it makes my left leg go numb only my left and makes it feel like it's really heavy. What should I do? Any suggestions?
