Need help pls

Amanda • My husband and I have been married for 5yrs. We`re currently expecting #3 and couldn`t be happier!
I've taken strip tests for 2 days now (wondfo brand) and both of them had a small dye run where the 2nd line would be. As a result, it's easy to see the outlines of the 2nd lines but there's no definite color. It just kind of looks shadowed. I'm 8DPO today. Is this possibly a BFP in the making or do I have the worlds worst batch of tests? Anyone else have this happen 2 days in a row? I'm driving myself nuts staring at them trying to figure out if it's "something" or not. Tried to post a pic in another thread and the pics are posting blurry.
