Faint pos cheapie then bfn frer fmu!

Ch

ladies I feel so shit. yesterday I decided to take a cheapie test (4 days before af is due) and waited a couple of mins then got fed up as it's always negative and I couldn't be bothered to wait. so I chucked it in the bin before waiting the full time. anyway I'm getting in to bed last night and decided to look at it and I was like HOLY CRAP.....

I'm in disbelief because I can see a line without squinting! It's really there and even my husband can see it. so I went out this morning after emptying my entire bladder into a cup and saving it and bought a frer. BFN!

I'm so confused and feel like life is playing one of its nasty tricks and the the cheap £1 test is probably faulty. has anyone had this happen and actually been pregnant? Or know of this happening to someone else? me and my husband have just been referred to the fertility clinic and have been ttc for 3 1/2 years.
