I am currently 13 weeks pregnant and suffering with awful pain in the left side of my pelvic. Is very uncomfortable to lay or turn in bed and causing me a lot of discomfort during the night and not able to sleep. It feels like the bone is grinding together, the pain shoots through to my lower back and leg. What should I do and is there anything that I can do to prevent this?

There is so much going on that I can't even hazzard a guess at this. I would consult your OB at your next appointment. Could be a pregnancy symptom but could be something else.
