I feel like I'm loosing my mind... Tw tests.

So I know the frer are clearly positive... But the others aren't showing any signs of anything. I know I'm a poas addict, but dang if my hcg is supposed to be doubling, wouldn't they start showing on the cheapies? I also feel like my test from this mornings line is not as dark as previous ones?

I guess I'm just freaking out because I've had previous chemicals and these tests look exactly the same as the ones from previous months.
