Those qualative tests aren't any better than the OTC urine tests though! I think you def could have a shot still! The positive I got on 15dpo was so light, nobody could see it but me pretty much lol. And now at 17dpo (supposedly) it is finally looking like a decent line that everyone can see. So either I implanted REALLY late this time, like much later than any of my other pregnancies...or I ovulated alot later than I ever did with any other pregnancy. Either way, I swore I would never be one of those women that had low temps, no positive hpt by the day my period was due, etc and still be pregnant. I mean, how could I be? After 5 very normal average pregnancies, it just wouldn't change all of a sudden...right? Wrong! It can happen for sure!
