I have a faint positive on a up&up target blue dye ... Positive came up at about 3 minutes. I'm 11dpo been spotting since 9dpo and today there is a lot more "spotting" sorry if this is TMI... But it's gone from slight pink to brown, dark red, and now kind of black... I'm on cd 25 my cycles are 28-30 days. Could I be pregnant or am I just wishful thinking and AF is coming? Could I of had the start to a pregnancy and ended as a chemical again?
