Surface water movement takes place in the form of currents. Currents move ocean water horizontally at the ocean's surface. Surface currents are driven mainly by the wind. Other forces such as the Coriolis effect and the location of landmasses do affect surface current patterns.
If the line is darker I would assume a BFP. Normally as Ovidrel leaves your system the line will get lighter. I was told by my doc that it could take at least 10 days to leave your system...which is why we're not suppose to test before day 14 (like any of us can wait that long). Congrats and best wishes to you!
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.
