I am starting to become so obsessed with pregnancy atm.
Just did another POAS - this time an extremely faint line on a Crystal Clear.
My positive one was on a Discover.

I believe you only need levels of HCG between 5-50mIU/ml.

Crystal Clear can detect up to 25mIU/ml, Discover 15mIU/ml.

I am still confused though, as I had a Pregnyl injection on Sunday.....
