Gather round, fellow POASers. 
Today, at 7 weeks pregnant, I decided to POAS for fun(?). 
It was light! 
So I remembered the good ole hook effect. When your hcg reaches a certain level, the test gets lighter. I added water to my sample and retested. DARK again. 
Confusing, right. I’m done POAS for 9 months. 
Dont fall for the hook effect.
