How many DPO did you get your BFP?
I'm currently 11dpo and testing negative. This is month 18 of ttc so I'm not holding much hope but usually I have strong signs my period is on it's way (spotting etc.) from about 7/8dpo and so far nothing... I'm praying for a miracle at this stage so I'm hoping 11dpo is still too early for a BFP!!
