This is my 6th cycle of TTC and I'm 15dpo. AF due today. I did a clear blue early detection test yesterday morning and one this morning. Both quite faint bfps which got a bit darker when they dried. I've been having weird cramps all day a bit like AF is coming but also slightly different and my bbt was raised more than normal this morning. Anyway I am worried because the lines seem faint and I've heard you can get evaporation lines on blue dye tests! May be paranoid but I really don't want to get my hopes up especially as I've been cramping and having watery discharge all day. Does anyone have experience of faint lines being false positives? DH could see the lines as well but they were squinters!
