I don't think you can stop them. When I was about 7 months pregnant I had these pains so awful I thought I would just croak. I do not know what causes them but I do remember eating spicy foods. Do you? Maybe best to back off if you do. Sorry aches and pains are just part of pregnancy. I know it is hard but you will survive. I had so much pain. I had back pain, stomach pain, pelvic pain, leg pain.
