So lost ladies no Af today

Fallon
Hello ladies ! So this is my first time using this app. And I love it .. So here's the deal .. Me and my fiance are TTC our 3rd baby .. I have a son from previous relationship who is 6 and our daughter who is 4 .. We have been trying on and off for about 8 months now .. My last visit from AF was 12/21/15 she was due today and nothing ... But going back I usually know my body pretty well especially when I'm ovulating .. I get mild cramps with tons of ewcm !! I have a regular 28-30 day cycle as well ... So about a week after supposed O day I had AF like cramping I kept checking to see if it was her but just wet/creamy CM .. This lasted about 3 days off and on.. Then I felt bad low back pain and felt nausea about two nights ago but for almost a week straight been having horrible breast pain and usually I do get this with PMS but it was different this time the pain was located on my armpits and sides of my tatas and I never really felt that with PMS they are really full they hurt when I run or walk up steps and when I raise my arms .. Not to mention the emotional rollercoaster I have been on .. I took 3 dollar store test all negative !! I bought clear blue advance weeks estimate so I'm gonna wait a few more days and try again with fmu the other tests were not fmu ... My question is ladies has anyone gotten lots of negatives before the BFP ?? Any comments will help thanks
