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).
The difference between the two tests is when they can detect hCG. Blood testing can detect hCG about eight to ten days after ovulation and in most cases urine testing (home pregnancy tests) detect hCG about two weeks after ovulation. The level of hCG is measured with a blood test known as a quantitative test, usually called a âquant betaâ by doctors.
