So I miscarried in early march and my levels were followed down to zero. I am now 11dpo after my first cycle. I took a dollar tree yesterday and got a very faint positive only after 15 min mark though. I took one today w/ FMU and another faint positive with 2-3 min. The problem is I stuck the test in my pocket and went about my day, taking it out every once in a while to see if the faint line is still there. I just took it out to look at it again and now there is a THIRD faint line in between to control line and the original faint line. Does this mean test is invalid???! I have a test ready to go for the AM, but it's going to be a longggg night wondering what's happening.
