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!
If you used an OPK you probably Ovulated about 24 hours after a positive test.)After Ovulation, if the sperm were available and conception took place, then it takes about 4 - 12 days for the fertilized egg to make the journey down the fallopian tube and find a prime place to burrow into the rich lining of the uterus.
