I tested today after wanting to throw the stupid flashing face against the wall for the last week!!! I got a solid face today :) and I also tested today and yesterday with cheap opk tests and today's line is much much darker than yesterdays. Not extremely dark but I did use first morning urine, and it only detects LH rise so will be the darkest tomorrow, where as clearbue gives you a solid face for 48h after testing.

Guess I was just 2days late this cycle
