16 days late BFNs anyone going through the same???

A
So now at 16days late gave up home testing haven't tested since the doctors on Thursday! Every test has been BFN no vvvfl nothing 😫 AF is never over a few days 2 at the most late, no sore boobs/nipples, have been bloated and had cramps,sore lower back,bit more discharge than normal(i know tmi sorry)but to me it feels normal like AF is going to happen but nothing!? 
Anyone in the same boat??
Got bloods on Tuesday to find out more xx
