..too early even for a sensitive test? (1st response).m I know it says 5 days before AF due but I'm sure I've heard a +ve result can be had earlier. Did one but it is -ve.Really want it to be +ve. Am really really tired - even on waking, but this could be as AF due nest wk. (Weds). Am I just testing too early because I'm so impatient for a BFP?
