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!
fertility tests Fertility ovulation sex ovulation predictor kit (OPK). Test every 12 hours not every 24 hours. The perfect time for sexual intercourse is within 12-24 hours prior to the ovulation predictor FIRST turning positive. Especially if you test only once a day. This may sound like a surprise, but making love only after first getting a positive OPK may not get you pregnant at all.
