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!
We tried on our own for four more months after that and had three failed IUI afterwards. Now we're planning to do IVF in November. I was told to have some blood tests on day 3 of my cycle in October and start taking birth control pills from now on to rest my ovaries. I guess I haven't read or heard about taking birth control pills for a month before the IVF cycle, and so just want to make sure it's the right thing to do.
