Chemical? :-(

Hi ladies,

I’m about 3 days late and have been testing positive since 10dpo. It was getting darker until I opened a new box of cheapie tests. With the new box the line is barely there now but still visible. Definitely lighter than before. Yesterday I spotted pink only when I wiped so I’m assuming this could be a chemical but still no period. I’m not sure what to think. For those of you that experienced chemical pregnancies, how long after your lines faded did AF show? Did you have light pink spotting beforehand? I’m not cramping and my boobs are still tingly. Has anyone experienced a box of cheapie tests (Pregmate) that were not accurate or faulty? Not sure what to think right now. Thanks.
