I see a line on all 3 pictures. I have been having faint lines too for the last 2 days, and Im reading that if they are within the time limit they are correct, even if its very faint. But I know of a few women who read tests outside of the time limit and it was postive and they really were pregnant. My friend did this years ago and she was pregnant. She was not TTC back then so I dont think she mentioned how much time had passed, ( and if she did I would not remember), she just told me thats what happend.
But then I have also read of women who werent pregnant when this happened. Sometimes it showed up within the time limit and sometimes it was after. Lot of stories about situations like this online.
I have done some experimenting on HPTs in my days, and I have never seen an evaporation line, nor has a test turned positive even days later. The only time I had one later turn positve was a test that was over 6 months old. I used wondofo brand hcg strips last month too, and I never got an evaporation line or a false positive after the allotted time passed, but since its kinda common with that brand I am not trusting the results of that particular brand. I have never used the ones you have, but I from what I have read if its within the time limit then its positive. I really hope you get your baby!
