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!

Hi Laura take a look at my pics, you will always get a faint +ve on an opk as the hormone is in your system constantly but rises significantly before ov - hence the test line gest darker before you ov indicating that there is more hormone. CD13 and 14 are the +ve tests.
