POAS addict and very faint lines!
I am 12/13 dpo and have faint (very faint lines) and AF was expected yesterday. The faint lines were visible on FRER with FMU and I took a CB digi to just confirm. But I got a BFN and tested with a faint line apparent on the wal mart cheapie. What in the what! I am also experiencing lower back pain, fatigue (I do have a 20 month old-I acutally always tired), no soreness, even had pink cm yesterday. Ahhhh. My first pregnancy was pretty straight forward and I got a very obvious positive on 12dpo. -Still hopeful.
