Pelvic Pain

This week I started experiencing pelvic pain, a little back pain but mostly in the front... it was like 31 weeks hit on Monday and BAM bad pelvic pain. Doctor just recommended no bending at the waist, getting on one knee if needing to pick stuff up... I notice it most when walking and at times it is super painful where I feel like I need to stop, just a throbbing pain on the front of my vaginal area. Any suggestions? Anything that's worked for other mommies??
