LOL annie reeeelllaaaaaax. It takes a few days for your hormone levels to increase enough to notice a significant difference on an hpt. Also, the cheapies (wondfo and others) don't pick up the change in colour as much as a FRER. I posted some pics of my 13dpo test today. Interestingly, from 10dpo to 11dpo there was barely any change. But when I left it from 11 dpo to 13 dpo it got a lot darker. If I were you, I would stop freaking out and don't test again until 14dpo. Then you will have your answer. Any other tests that you do in the meantime are just fuelling doubts for you. KWIM?
hugs!! xx
