Ovulation test question..

Kristina

So I get that when the two lines are the same color that means you will be ovulating within so many hours. Earlier today, this morning, I had a positive. Now tonight at 10:00pm the line is getting lighter.

Does that mean the time had passed and my egg has left so my window for conceiving is done this month? Or is the egg there until the line is pretty much gone??

Just wondering..
