Ok so I have been testing since 8dpo getting bfn until today I am 11dpo and I got a faint line on a cheapie (clear&simple;) with fmu at 7am...I went to work and held my pee the whole time till 1.30pm then I went home and tested again with the same brand and got another faint line...so I got all excited and got the expensive tests out (first response) and got a huge BFN not even a hint of a line!!!! What’s going on! I had a temp dip yesterday and have been having dizzy spells since I just don’t know what to think has anyone else been in this situation?
