AF is late...

So AF is late by 1 day according to this and 2 days according to pink pad....I tested last night and got a bfn on a frer?!
​I am not getting any pregnancy symptoms....just mild cramping on and off, milky cm and I am a bit gassy (I usually get like that around AF)
​I believe the pregnancy test but am frustrated, wish she would just show up already!!! 
​Any thoughts? Xx
