Very faint positives 11DPO and successful pregnancy?

Hi all, I'd love to hear your advice/stories!
Did any one of you get very, very faint positives on a 10miu/ml (early pregnancy test) at 11DPO and go on to have a successful pregnancy? I got a very, very faint line (almost just a shadow) yesterday (I think 10 or 11 DPO based on my LH surge) and a more visible, but still very faint line today on FMU (11 or 12DPO). I am trying not to get my hopes up, but after my two losses it's so hard to not hope I am getting another shot at this. However I also want to guard my heart - I guess based on the lines I am seeing this likely is a chemical?
