Adhesions typically begin to form within the first few days after surgery, but they may not produce symptoms for months or even years. As scar tissue begins to restrict motion of the small intestines, passing food through the digestive system becomes progressively more difficult. The bowel may become blocked.
At the time of implantation, the placenta starts making the pregnancy hormone hCG, which then enters the blood stream. hCG can be detected in the blood about 3 to 4 days after implantation. Urine hCG can be detected about 2 to 3 days after blood hCG can first be seen. Detection of hCG depends on timing of implantation so hCG can normally be detected in the blood between 9 and 16 days after ovulation (HPT: 12-19 days after ovulation).
Human chorionic gonadotropin (hCG) is a hormone produced by the placenta of a pregnant woman. Early in pregnancy, the level of hCG increases in the blood and is eliminated in the urine. A pregnancy test detects hCG in the blood or urine and confirms or rules out pregnancy. During the early weeks of pregnancy, hCG is important in maintaining function of the corpus luteum. Production of hCG increases steadily during the first trimester (8-10 weeks) of a normal pregnancy, peaking around the 10 th week after the last menstrual cycle.
