Aww, I understand! Mine are irregular too. I do want to add from what I said above that I have used these test. With me, I got an almost positive, really close to being as dark as the control line, still considered negative, but I got positives from two other brands...all three with the same urine sample...So, from now on, since I have many of these tests, when these look almost positive, I am going to back it up with with a clearblue digital for confirmation. These didnt work for a straight up positive for me, but they might for others. I have pictures with comparison, if I can figure out how to upload them.
