OOO---- I see a faint line on that FRER and I saw lines on the other one's too. Have you tried to do a double dye test yet? Make sure you use PT dye strips to double it, not dye from an OPK, but I bet it would tell you for sure if you were or not. You'll need two test's though. Can you get a hold of the .88cent walmart test's or the 1 dollar dollar general ones? You want either two IC's or two cheap cassettes that when opened are really just an IC laid in it, they are easier to take apart and put back together.
