What is happening? Late AF not usual in me

I have some symptoms that makes me think I am pregnant (including cramps, vomiting and acne and it is not normal at all in me, just the cramps). AF was supposed to come on 02/22 or 02/23 ( I have been tracking my cycle since july/2017... my shortest cycle was 29 and my longest 32 days)... I had 3 early pregnancy test (including one today when is not early anymore)... 3 BFN, I don’t have idea what is happening 😖🤷🏻‍♀️

This is today’s test. I don’t see anything, but do you??
