well, I'm sorry that they aren't amounting to anything, I know you really want another LO.
I noticed that this isn't the first time you had the same issue with lines of all of your tests. Didn't you test with faint lines for around two weeks last cycle also?
Since you have PCOS (which you mentioned before). You might just have a cyst or some other reason for always getting a faint line on the early tests. Maybe early tests are too sensitive for your body and you could relieve this heartache by testing with the less sensitive tests after you miss AF once you start TTC?
