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!

I know the saying is usually 24-36 hours after a positive OPK that you actually ovulate but have any of you actually noticed a pattern with yourself, do you think you seem to typically O sooner then 24-36 hours after a postive, longer than that? Or about in that range. I think I notice I usually O close to 20-24 hours after a positive OPK...most of the time...I usually have a positve OPK by today which is CD 13, but its still negative, but barley, line is almost as dark as the control line but not quite, it will certainly be positive tomorrow.
