Test advice/ help

Bianca
Yesterday I was 11 dpo and showing all the pregnancies symptom, I couldn't help but test. It came back with a very light positive. This morning I thought I will try It again at 12dpo for a darker line (different brand -first response-) and it came back negative. Now I have no idea what to think?! I'm so confused! Has this happened to anyone ?? If so please explain!
