Do not do anything in attempt to loose your mucous plug. It may have already came out but in small amounts so you may not have noticed. Talk to your doctor and use his advice. I know it's hard waiting for your baby but believe it or not you will not be pregnant forever and the baby will come out when the baby is completely developed. Development including gaining fat in the last month of pregnancy, which is extremley important. You will soon get to meet your new baby, try to enjoy the rest of your pregnancy even though you are uncomfortable; believe it or not you will miss being pregnant someday.
