Frustrated!

Late on AF so took 3 tests yesterday and all were BFP, went to dr today and their test showed negative so they did blood work (waiting for results) so after I left I went to work and took another test and again, BFP. Went to the store and bought 3 different test and again all three this evening was BFP, so I have had 7 hpt BFP and then the doctors negative! Ugh anyone else dealt w this!?
