Pregnancy is the term given to the series of events for a childbearing woman from the time of conception until the birth of the child.
During the third trimester, continuing growth and development in mother and baby cause many changes to occur. Women may notice: that the movements of the unborn child can be felt more stronglyabdominal pain that may or may not represent the start of labor shortness of breath because the uterus is pushing against the diaphragm. The diaphragm is a flat, strong muscle that aids in breathing. Towards the end of the third trimester, the baby may drop down into a lower position. This will make it easier for the mother to breathe.a need to urinate more often when the baby drops down into a lower position in the pelvisa yellow, watery fluid, known as colostrum, leaking from her nipplesher navel sticking out

At 40 weeks, the baby is considered full term. It is about 20 inches long and weighs 6 to 9 pounds. The most common health risks and concerns in the third trimester of pregnancy are: premature labor beginning before the 37th week of pregnancy. If the labor cannot be stopped, the baby may be born too early. This can cause many problems with the baby's health and development.vaginal bleeding changes in the unborn child's movementsrupture of the sac, or membranes, that surround the fetusfalse labor
During the third trimester of pregnancy, monitoring is more frequent. In the seventh and eighth months, it may include: mother's weight and blood pressureurine test for sugar and proteinthe baby's heartbeatheight of the uterussize and position of the baby
Any worrisome symptoms or concerns should be reported to the healthcare professional.
After the 32nd week, the healthcare professional may suggest monitoring every two weeks. Monitoring occurs weekly after about the 36th week, as the ninth month begins. It may include all of the above as well as examination of the cervix and discussion about the signs and symptoms of labor.
